Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Note 1) Business Valley National Bancorp, a New Jersey Corporation (Valley), is a bank holding company whose principal wholly-owned subsidiary is Valley National Bank (the “Bank”), a national banking association providing a full range of commercial, retail and trust and investment services through its branch and ATM network throughout northern and central New Jersey, the New York City boroughs of Manhattan, Brooklyn, Queens, Long Island, and southeast and central Florida. The Bank also lends to borrowers outside its branch network. The Bank is subject to intense competition from other financial services companies and is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by certain regulatory authorities. Valley National Bank’s subsidiaries are all included in the consolidated financial statements of Valley. These subsidiaries include: • an all-line insurance agency offering property and casualty, life and health insurance; • asset management advisers which are Securities and Exchange Commission (SEC) registered investment advisors; • title insurance agencies in New Jersey, New York and Florida; • subsidiaries which hold, maintain and manage investment assets for the Bank; • a subsidiary which owns and services auto loans; • a subsidiary which specializes in health care equipment lending and other commercial equipment leases; • a subsidiary which owns and services general aviation aircraft loans and existing commercial equipment leases; and • a subsidiary which owns and services New York commercial loans. The Bank’s subsidiaries also include real estate investment trust subsidiaries (the “REIT” subsidiaries) which own real estate related investments and a REIT subsidiary which owns some of the real estate utilized by the Bank and related real estate investments. Except for Valley’s REIT subsidiaries, all subsidiaries mentioned above are directly or indirectly wholly-owned by the Bank. Because each REIT subsidiary must have 100 or more shareholders to qualify as a REIT, each REIT subsidiary has issued less than 20 percent of its outstanding non-voting preferred stock to individuals, most of whom are non-senior management Bank employees. The Bank owns the remaining preferred stock and all the common stock of the REITs. Basis of Presentation The consolidated financial statements of Valley include the accounts of its commercial bank subsidiary, Valley National Bank and all of Valley’s direct or indirect wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated. The accounting and reporting policies of Valley conform to U.S. generally accepted accounting principles (U.S. GAAP) and general practices within the financial services industry. In accordance with applicable accounting standards, Valley does not consolidate statutory trusts established for the sole purpose of issuing trust preferred securities and related trust common securities. See Note 11 for more details. Certain prior period amounts have been reclassified to conform to the current presentation. In preparing the consolidated financial statements in conformity with U.S. GAAP, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and results of operations for the periods indicated. Material estimates that are particularly susceptible to change are: the allowance for loan losses; the evaluation of goodwill and other intangible assets, and investment securities for impairment; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates. The current economic environment has increased the degree of uncertainty inherent in these material estimates. On December 1, 2015, Valley completed its acquisition of CNLBancshares, Inc. and its wholly-owned subsidiary, CNLBank, headquartered in Orlando, Florida. On November 1, 2014, Valley acquired 1st United Bancorp, Inc. (1st United) and its wholly owned subsidiary, 1st United Bank, a commercial bank. Both CNLBank and 1st United Bank were immediately merged with and into Valley National Bank at the respective dates of acquisition. See the supplemental schedule of non-cash investing activities of the Consolidated Statements of Cash Flows and Note 2 for additional information regarding these acquisitions. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits in other banks (including the Federal Reserve Bank of New York) and, from time to time, overnight federal funds sold. The Bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank based on a percentage of deposits. These reserve balances totaled $304.0 million and $45.5 million at December 31, 2015 and 2014 , respectively. Investment Securities At the time of purchase, management elects to classify investment securities into one of three categories: held to maturity, available for sale or trading. Investment securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold to maturity. Investment securities to be held for indefinite periods are classified as available for sale and carried at fair value, with unrealized holding gains and losses reported as a component of other comprehensive income or loss, net of tax. Securities that may be sold and reinvested over short durations as part of management’s asset/liability management strategies are classified as trading and are carried at fair value, with changes in unrealized holding gains and losses included in non-interest income in the accompanying consolidated statements of income as a component of net trading gains. Realized gains or losses on the sale of available for sale and trading securities are recognized by the specific identification method and are included in net gains on securities transactions and other non-interest income, respectively. Investments in Federal Home Loan Bank and Federal Reserve Bank stock, which have limited marketability, are carried at cost in other assets. Quarterly, Valley evaluates its investment securities classified as held to maturity and available for sale for other-than-temporary impairment. Other-than-temporary impairment means Valley believes the security’s impairment is due to factors that could include the issuer’s inability to pay interest or dividends, the potential for default, and/or other factors. When a held to maturity or available for sale debt security is assessed for other-than-temporary impairment, Valley has to first consider (a) whether it intends to sell the security, and (b) whether it is more likely than not that Valley will be required to sell the security prior to recovery of its amortized cost basis. If neither of these circumstances applies to a security, but Valley does not expect to recover the entire amortized cost basis, an other-than-temporary impairment loss has occurred that must be separated into two categories: (a) the amount related to credit loss, and (b) the amount related to other factors. In assessing the level of other-than-temporary impairment attributable to credit loss, Valley compares the present value of cash flows expected to be collected with the amortized cost basis of the security. The portion of the total other-than-temporary impairment related to credit loss is recognized in earnings, while the portion related to other factors is recognized in other comprehensive income or loss. The total other-than-temporary impairment loss is presented in the statement of income, less the portion recognized in other comprehensive income or loss. When a debt security becomes other-than-temporarily impaired, its amortized cost basis is reduced to reflect the portion of the total impairment related to credit loss. There was no other-than-temporary impairment recognized in earnings as a result of Valley's impairment analysis of its securities during 2015 , 2014 and 2013 . To determine whether a security’s impairment is other-than-temporary, Valley considers factors that include, among others, the causes of the decline in fair value, such as credit problems, interest rate fluctuations, or market volatility; the severity and duration of the decline; Valley’s ability and intent to hold equity security investments until they recover in value (as well as the likelihood of such a recovery in the near term); Valley’s intent to sell security investments; and whether it is more likely than not that Valley will be required to sell such securities before recovery of their individual amortized cost basis. For debt securities, the primary consideration in determining whether impairment is other-than-temporary is whether or not it is probable that current and/or future contractual cash flows have been or may be impaired. See the “Other-Than-Temporary Impairment Analysis” section of Note 4 for further discussion. Interest income on investments includes amortization of purchase premiums and discounts. Realized gains and losses are derived based on the amortized cost of the security sold. Valley discontinues the recognition of interest on debt securities if the securities meet both of the following criteria: (i) regularly scheduled interest payments have not been paid or have been deferred by the issuer, and (ii) full collection of all contractual principal and interest payments is not deemed to be the most likely outcome, resulting in the recognition of other-than-temporary impairment of the security. Loans Held for Sale Loans held for sale generally consist of conforming residential mortgage loans originated and intended for sale in the secondary market and are carried at their estimated fair value on an instrument-by-instrument basis as permitted by the fair value option election under U.S. GAAP. Changes in fair value are recognized in non-interest income in the accompanying consolidated statements of income as a component of net gains on sales of loans. Origination fees and costs related to loans held for sale are recognized as earned and as incurred. Loans held for sale are generally sold with loan servicing rights retained by Valley. Gains recognized on loan sales include the value assigned to the rights to service the loan. See “Loan Servicing Rights” section below. From time to time, Valley may elect to transfer non-performing loans from commercial and industrial or commercial real estate portfolios. At December 31, 2014 , loans held for sale included one non-performing commercial real estate loan totaling $7.1 million . Loans and Loan Fees Loans are reported at their outstanding principal balance net of any unearned income, charge-offs, unamortized deferred fees and costs on originated loans and premium or discounts on purchased loans, except for purchased credit-impaired loans. Loan origination and commitment fees, net of related costs are deferred and amortized as an adjustment of loan yield over the estimated life of the loans approximating the effective interest method. Loans are deemed to be past due when the contractually required principal and interest payments have not been received as they become due. Loans are placed on non-accrual status generally, when they become 90 days past due and the full and timely collection of principal and interest becomes uncertain. When a loan is placed on non-accrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current income. Payments received on nonaccrual loans are generally applied against principal. A loan in which the borrowers’ obligation has not been released in bankruptcy courts may be restored to an accruing basis when it becomes well secured and is in the process of collection, or all past due amounts become current under the loan agreement and collectability is no longer doubtful. Purchased Credit-Impaired Loans (Including Covered Loans) Purchased credit-impaired (PCI) loans are loans acquired at a discount (that is due, in part, to credit quality). Valley's PCI loan portfolio primarily consists of loans acquired in business combinations subsequent to 2011 and (covered) loans in which the Bank will share losses with the FDIC under loss-sharing agreements that have resulted from past FDIC-assisted transactions by Valley and 1st United acquired in 2014. The PCI loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no allowance for loan losses. Beginning in 2010, Valley has accounted for interest income on all loans acquired at a discount (that is due, in part, to credit quality) based on the acquired loans’ expected cash flows. The PCI loans may be aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. A pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flow. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income utilizing the level-yield method over the life of each pool. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or an allowance for loan losses. Increases in expected cash flows subsequent to the acquisition are recognized prospectively through adjustment of the yield on the pool over its remaining life, while decreases in expected cash flows are recognized as impairment through a loss provision and an increase in the allowance for loan losses. Therefore, the allowance for loan losses on these impaired pools reflect only losses incurred after the acquisition (representing the present value of all cash flows that were expected at acquisition but currently are not expected to be received). Any allowance for loan losses related to covered PCI loans is determined without consideration of the amounts recoverable through the FDIC loss-share agreements (see “FDIC Loss-Share Receivable” below). Valley had no allowance reserves related to PCI loans at December 31, 2015 as compared to $200 thousand (all related to covered PCI loans) at December 31, 2014. The Bank periodically evaluates the remaining contractual required payments due and estimates of cash flows expected to be collected for the underlying loans of each PCI loan pool. These evaluations, performed quarterly, require the continued use of key assumptions and estimates, similar to the initial estimate of fair value. Changes in the contractual required payments due and estimated cash flows expected to be collected may result in changes in the accretable yield and non-accretable difference or reclassifications between accretable yield and the non-accretable difference. For the pools with better than expected cash flows, the forecasted increase is recorded as an additional accretable yield that is recognized as a prospective increase to our interest income on loans and the FDIC loss-share receivable, if applicable, is prospectively reduced by the guaranteed portion of the additional cash flows expected to be received, with a corresponding reduction to non-interest income. See Note 5 for additional information. PCI loans that may have been classified as non-performing loans by an acquired bank are no longer classified as non-performing because these loans are accounted for on a pooled basis. Management’s judgment is required in classifying loans in pools as performing loans, and is dependent on having a reasonable expectation about the timing and amount of the pool cash flows to be collected, even if certain loans within the pool are contractually past due. Allowance for Credit Losses The allowance for credit losses (the “allowance”) is increased through provisions charged against current earnings and additionally by crediting amounts of recoveries received, if any, on previously charged-off loans. The allowance is reduced by charge-offs on loans or unfunded letters of credit which are determined to be a loss, in accordance with established policies, when all efforts of collection have been exhausted. The allowance is maintained at a level estimated to absorb probable credit losses inherent in the loan portfolio as well as other credit risk related charge-offs. The allowance is based on ongoing evaluations of the probable estimated losses inherent in the non-PCI loan portfolio and off-balance sheet unfunded letters of credit, as well as reserves for impairment of PCI loans subsequent to their acquisition date. As discussed under the “Purchased Credit-Impaired Loans” section above, the allowance for credit losses at December 31, 2014 included reserves for impairment of covered PCI loans subsequent to their acquisition date that were reduced to zero at December 31, 2015 through loan charge-offs recognized during 2015. The Bank’s methodology for evaluating the appropriateness of the allowance includes grouping the non-covered loan portfolio into loan segments based on common risk characteristics, tracking the historical levels of classified loans and delinquencies, estimating the appropriate loss look-back and loss emergence periods related to historical losses for each loan segment, providing specific reserves on impaired loans, and assigning incremental reserves where necessary based upon qualitative and economic outlook factors including numerous variables, such as the nature and trends of recent loan charge-offs. Additionally, the volume of non-performing loans, concentration risks by size, type, and geography, new markets, collateral adequacy, credit policies and procedures, staffing, underwriting consistency, loan review and economic conditions are taken into consideration. The allowance for loan losses consists of four elements: (i) specific reserves for individually impaired credits, (ii) reserves for adversely classified, or higher risk rated, loans that are not impaired, (iii) reserves for other loans based on historical loss factors (using the appropriate loss look-back and loss emergence periods) adjusted for both internal and external qualitative risk factors to Valley, including the aforementioned factors, as well as changes in both organic and purchased loan portfolio volumes, the composition and concentrations of credit, new market initiatives, and the impact of competition on loan structuring and pricing, and (iv) an allowance for PCI loan pools impaired subsequent to the acquisition date, if applicable. The Credit Risk Management Department individually evaluates non-accrual (non-homogeneous) commercial and industrial loans and commercial real estate loans over $250 thousand and all troubled debt restructured loans. The value of an impaired loan is measured based upon the underlying anticipated method of payment consisting of either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, if the loan is collateral dependent, and its payment is expected solely based on the underlying collateral. If the value of an impaired loan is less than its carrying amount, impairment is recognized through a provision to the allowance for loan losses. Collateral dependent impaired loan balances are written down to the estimated current fair value (less estimated selling costs) of each loan’s underlying collateral resulting in an immediate charge-off to the allowance, excluding any consideration for personal guarantees that may be pursued in the Bank’s collection process. If repayment is based upon future expected cash flows, the present value of the expected future cash flows discounted at the loan’s original effective interest rate is compared to the carrying value of the loan, and any shortfall is recorded as a specific valuation allowance in the allowance for loan losses. Accrual of interest is discontinued on an impaired loan when management believes, after considering collection efforts and other factors, the borrower’s financial condition is such that collection of interest is doubtful. Cash collections on impaired loans are generally credited to the loan balance, and no interest income is recognized on these loans until the principal balance has been determined to be fully collectible. Residential mortgage loans and consumer loans usually consist of smaller balance homogeneous loans that are collectively evaluated for impairment, and are specifically excluded from the impaired loan portfolio, except where the loan is classified as a troubled debt restructured loan. The allowances established for probable losses on specific loans are based on a regular analysis and evaluation of the loans. Loans are evaluated based on an internal credit risk rating system for the commercial and industrial loan and commercial real estate loan portfolio segments and non-performing loan status for the residential and consumer loan portfolio segments. Loans are risk-rated based on an internal credit risk grading process that evaluates, among other things: (i) the obligor’s ability to repay; (ii) the underlying collateral, if any; and (iii) the economic environment and industry in which the borrower operates. This analysis is performed at the relationship manager level for all commercial and industrial loans and commercial real estate loans, and evaluated by the Loan Review Department on a test basis. Loans with a grade that is below “Pass” grade are adversely classified. See Note 5 for details. Any change in the credit risk grade of performing and/or non-performing loans affects the amount of the related allowance. Once a loan is adversely classified, the assigned relationship manager and/or a special assets officer in conjunction with the Credit Risk Management Department analyze the loan to determine whether the loan is impaired and, if impaired, the need to specifically allocate a portion of the allowance for loan losses to the loan. Specific valuation allowances are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. Loans identified as losses by management are charged-off. Commercial loans are generally assessed for full or partial charge-off to the net realizable value for collateral dependent loans when a loan is between 90 or 120 days past due or sooner if it is probable that a loan may not be fully collectable. Residential loans and home equity loans are generally charged-off to net realizable value when the loan is 120 days past due (or sooner when the borrowers’ obligation has been released in bankruptcy). Automobile loans are fully charged-off when the loan is 120 days past due or partially charged-off to the net realizable value of collateral, if the collateral is recovered prior to such time. Unsecured consumer loans are generally fully charged-off when the loan is 150 days past due. The allowance allocations for other loans (i.e.; risk rated loans that are not adversely classified and loans that are not risk rated) are calculated by applying historical loss factors for each loan portfolio segment to the applicable outstanding loan portfolio balances. Loss factors are calculated using statistical analysis supplemented by management judgment. The statistical analysis considers historical default rates, historical loss severity in the event of default, and the average loss emergence period for each loan portfolio segment. The management analysis includes an evaluation of loan portfolio volumes, the composition and concentrations of credit, credit quality and current delinquency trends. Prior to December 31, 2015, the allowance also contains reserves to cover inherent losses within each of Valley’s loan portfolio segments, which have not been otherwise reviewed or measured on an individual basis. Such reserves include management’s evaluation of loan portfolio volumes, the composition and concentrations of credit, as well as other trends within the loan portfolio. These reserves reflected management’s attempt to ensure that the overall allowance reflected a margin for imprecision and the uncertainty that is inherent in estimates of probable incurred credit losses. As part of an ongoing evaluation process of developing the allowance for credit losses estimate, management continually evaluates and updates their assumptions based on the current economic environment and their own loss experience. During the fourth quarter of 2015, Valley refined and enhanced its assessment of the adequacy of the allowance for loan losses by extending the loss look-back period on the majority of its loan portfolios from three years to four years in order to capture more of the current economic cycle as it continues. Valley also enhanced its qualitative factor framework to capture the risks of several factors, including, but not limited to, the impact of changes in capitalization rates on collateral values, concentrations of certain loan types, including multi-family and exculpated loans, the volume of loans purchased from and serviced by third parties, as well as the rate of growth in Valley's real estate portfolios. These enhancements are meant to increase the level of precision in the allowance for credit losses. As a result, Valley will no longer have an “unallocated” segment in its allowance for credit losses, as the risks and uncertainties meant to be captured by the unallocated allowance have been included in the qualitative framework for the respective portfolios at December 31, 2015. As such, the unallocated allowance has in essence been reallocated to the certain portfolios based on the risks and uncertainties it was meant to capture. See Notes 5 and 6 for Valley’s loan credit quality and additional allowance disclosures. Premises and Equipment, Net Premises and equipment are stated at cost less accumulated depreciation computed using the straight-line method over the estimated useful lives of the related assets. Generally, these useful lives range from three to forty years. Leasehold improvements are amortized over the term of the lease or estimated useful life of the asset, whichever is shorter. Major improvements are capitalized, while repairs and maintenance costs are charged to operations as incurred. Upon retirement or disposition, any gain or loss is credited or charged to operations. See Note 7 for further details. Bank Owned Life Insurance Valley owns bank owned life insurance (BOLI) to help offset the cost of employee benefits. BOLI is recorded at its cash surrender value. Valley’s BOLI is invested primarily in U.S. Treasury securities and residential mortgage-backed securities issued by government sponsored enterprises and Ginnie Mae. The majority of the underlying investment portfolio is managed by one independent investment firm. The change in the cash surrender value is included as a component of non-interest income and is exempt from federal and state income taxes as long as the policies are held until the death of the insured individuals. Other Real Estate Owned Valley acquires other real estate owned (OREO) through foreclosure on loans secured by real estate. OREO is reported at the lower of cost or fair value, as established by a current appraisal (less estimated costs to sell), and is included in other assets. Any write-downs at the date of foreclosure are charged to the allowance for loan losses. Expenses incurred to maintain these properties, unrealized losses resulting from valuation write-downs after the date of foreclosure, and realized gains and losses upon sale of the properties are included in other non-interest expense. OREO and other repossessed assets totaled $19.0 million and $24.7 million (including $5.0 million and $9.2 million of OREO properties related to the FDIC-assisted transactions, which are subject to the loss-sharing agreements) at December 31, 2015 and 2014 , respectively. At December 31, 2015 , OREO included foreclosed residential real estate properties totaling $7.0 million . Residential mortgage and consumer loans secured by residential real estate properties for which formal foreclosure proceedings are in process totaled $12.3 million at December 31, 2015 . FDIC Loss-Share Receivable Valley National Bank has several loss-share agreements with the FDIC (referred to as the “FDIC loss-share receivable” reported within other assets on Valley’s consolidated statements of financial condition) which relate to the LibertyPointe Bank and The Park Avenue Bank transactions entered into by Valley in 2010, as well as three prior FDIC-assisted transactions by 1st United (including Republic Federal Bank, The Bank of Miami and Old Harbor Bank) acquired by Valley in 2014. The FDIC loss-share receivable arising from the loss-share agreements is measured separately from the covered loan pools because the agreements are not contractually part of the covered loans and are not transferable should the Bank choose to dispose of the covered loans. At the date of acquisition, the FDIC loss-share receivable was measured at its fair value based on expected future cash flows covered by the loss share agreements. In addition, the asset is based on the credit adjustments estimated for each loan pool and the loss-share percentages. At December 31, 2015 and 2014, our FDIC loss-share receivable totaled $8.3 million and $13.8 million , respectively. Although this asset represents a contractual receivable from the FDIC, there is no contractual interest rate associated with the asset. The difference between the present value and the undiscounted cash flow expected to be collected from the FDIC is accreted into non-interest income over the life of the FDIC loss-share receivable. Actual or expected losses in excess of the acquisition date estimates result in an increase in the FDIC loss-share receivable. Conversely, when actual or expected losses are less than the acquisition date estimates, the loss share receivable is decreased. This reduction is recognized prospectively over the shorter of (i) the estimated life of the respective pools of covered loans or (ii) the term of the loss-sharing agreements with the FDIC. The FDIC loss-share receivable is also reduced and increased as loss-sharing payments are received from and made to the FDIC. Effective January 1, 2015, the losses on commercial related loans (commercial and industrial loans and commercial real estate loans) from the Republic Federal Bank transaction ceased being covered under the loss-share agreement. Any recoveries, net of expenses, of losses incurred prior to January 1, 2015 on such loans will continue to be covered (and must be shared with the FDIC in accordance with the loss-share agreement) through December 31, 2017. The losses on consumer related loans (residential mortgage loans and consumer loans) continue to be covered under the loss-share agreement through December 31, 2019. Under the terms of this loss-sharing agreement with the FDIC, losses are shared on the acquired loan and other real estate owned portfolio between 80 percent and 95 percent based upon certain aggregate loss limits. Effective April 1, 2015, the losses on commercial related loans from the LibertyPointe Bank and The Park Avenue Bank transactions ceased to be covered under the loss-share agreements. Any recoveries, net of expenses, of losses incurred prior to April 1, 2015 on such loans will continue to be covered by the loss-sharing agreement through March 31, 2018. The losses on consumer related loans will continue to be covered under the loss-share agreements through March 31, 2020. Under the terms of the loss-sharing agreements for the LibertyPointe Bank and The Park Avenue Bank transaction, the FDIC is obligated to reimburse Valley for 80.0 percent and 95.0 percent , respectively, of any future losses on covered consumer loans up to certain aggregate loss limits. Effective January 1, 2016, the losses on commercial related loans from The Bank of Miami transaction ceased to be covered under the loss-share agreement. Any recoveries, net of expenses

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS (Note 2) CNLBancshares, Inc. On December 1, 2015, Valley completed its acquisition of CNLBancshares, Inc. (CNL) and its wholly-owned subsidiary, CNLBank, headquartered in Orlando, Florida, a commercial bank with approximately $1.6 billion in assets, $825 million in loans, $1.2 billion in deposits and 16 branch offices on the date of its acquisition by Valley. The common shareholders of CNL received 0.705 of a share of Valley common stock for each CNL share they owned prior to the merger. The total consideration for the acquisition was approximately $230 million , consisting of 20.6 million shares of Valley common stock. Merger expenses totaled $1.8 million for the year ended December 31, 2015, which largely related to professional and legal fees included in non-interest expense on the consolidated statements of income. Valley also recorded a $3.3 million charge within income tax expense for the fourth quarter of 2015 which mostly related to the effect of the CNL acquisition on the valuation of our deferred tax assets. The following table sets forth assets acquired and liabilities assumed in the CNL acquisition, at their estimated fair values as of the closing date of the transaction: December 1, 2015 (in thousands) Assets acquired: Cash and cash equivalents $ 201,025 Investment securities available for sale 327,264 Total loans 825,465 Premises and equipment 8,550 Bank owned life insurance 5,090 Accrued interest receivable 3,741 Goodwill 109,991 Other intangible assets 19,330 Other assets 49,894 Total assets acquired $ 1,550,350 Liabilities assumed: Deposits: Non-interest bearing $ 501,714 Savings, NOW and money market 562,187 Time 103,874 Total deposits 1,167,775 Short-term borrowings 57,087 Long-term borrowings 90,738 Accrued expenses and other liabilities 5,148 Total liabilities assumed $ 1,320,748 Common stock issued in acquisition $ 229,602 The determination of the fair value of the assets acquired and liabilities assumed required management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and subject to change. The fair value estimates are subject to change for up to one year after the closing date of the transaction if additional information (existing at the date of closing) relative to closing date fair values becomes available. As Valley continues to analyze the acquired assets and liabilities, there may be adjustments to the recorded carrying values. However, Valley does not expect significant future adjustments to the recorded amounts at December 31, 2015. Fair Value Measurement of Assets Acquired and Liabilities Assumed Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the CNL acquisition. Cash and cash equivalents. The estimated fair values of cash and cash equivalents approximate their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Investment securities. The estimated fair values of the investment securities were calculated utilizing Level 2 inputs. The prices for these instruments are obtained through an independent pricing service when available, or dealer market participants with whom Valley has historically transacted both purchases and sales of investment securities. The prices are derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviewed the data and assumptions used in pricing the securities by its third party provider to ensure the highest level of significant inputs are derived from market observable data. Loans. The acquired loan portfolio was segregated into categories for valuation purposes primarily based on loan type (commercial, mortgage, or consumer) and credit risk rating. The estimated fair values were computed by discounting the expected cash flows from the respective portfolios. Management estimated the cash flows expected to be collected at the acquisition date by using valuation models that incorporated estimates of current key assumptions, such as prepayment speeds, default rates, and loss severity rates. Prepayment assumptions were developed by reference to recent or historical prepayment speeds observed for loans with similar underlying characteristics. Prepayment assumptions were influenced by many factors including, but not limited to, forward interest rates, loan and collateral types, payment status, and current loan-to-value ratios. Default and loss severity rates were developed by reference to recent or historical default and loss rates observed for loans with similar underlying characteristics. Default and loss severity assumptions were influenced by many factors including, but not limited to, underwriting processes and documentation, vintages, collateral types, collateral locations, estimated collateral values, loan-to-value ratios, and debt-to-income ratios. The expected cash flows from the acquired loan portfolios were discounted at estimated market rates. The market rates were estimated using a buildup approach which included assumptions with respect to funding cost and funding mix, estimated servicing cost, liquidity premium, and additional spreads, if warranted, to compensate for the uncertainty inherent in the acquired loans. The methods used to estimate the Level 3 fair values of loans are extremely sensitive to the assumptions and estimates used. While management attempted to use assumptions and estimates that best reflected the acquired loan portfolios and current market conditions, a greater degree of subjectivity is inherent in these values than in those determined in active markets. The difference between the fair value and the expected cash flows from the acquired loans will be accreted to interest income over the remaining term of the loans in accordance with Accounting Standards Codification (ASC) Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” See Note 5 for further details. Other intangible assets. Other intangible assets consisting of core deposit intangibles (CDI) are measures of the value of non-maturity checking, savings, NOW and money market deposits that are acquired in a business combination. The fair value of the CDI is based on the present value of the expected cost savings attributable to the core deposit funding, relative to an alternative source of funding. The CDI is amortized over an estimated useful life of 11 years to approximate the existing deposit relationships acquired. Deposits. The fair values of deposit liabilities with no stated maturity (i.e., non-interest bearing accounts and savings, NOW and money market accounts) are equal to the carrying amounts payable on demand. The fair values of certificates of deposit represent contractual cash flows, discounted to present value using interest rates currently offered on deposits with similar characteristics and remaining maturities. Short-term borrowings. The short-term borrowings consist of securities sold under agreements to repurchase. The carrying amounts approximate their fair values because they frequently re-price to a market rate. Long-term borrowings. The fair values of long-term borrowings consisting of FHLB advances were estimated by discounting the estimated future cash flows using market discount rates for borrowings with similar characteristics, terms and remaining maturities. 1st United Bancorp, Inc. On November 1, 2014, Valley acquired 1st United Bancorp, Inc. (1st United) and its wholly-owned subsidiary, 1st United Bank, a commercial bank with approximately $1.7 billion in assets, $1.2 billion in loans, and $1.4 billion in deposits, before purchase accounting adjustments. The 1st United acquisition brought to Valley a 20 branch network covering some of the most attractive urban banking markets in Florida, including locations throughout southeast Florida, the Treasure Coast, central Florida and central Gulf Coast regions. The common shareholders of 1st United received 0.89 of a share of Valley common stock for each 1st United share they owned prior to the merger. The total consideration for the acquisition was approximately $300 million , consisting of 30.7 million shares of Valley common stock and $8.9 million of cash consideration paid to 1st United stock option holders. In conjunction with the merger, Valley shareholders approved an amendment of its certificate of incorporation to increase its authorized common shares by 100 million shares during the third quarter of 2014. Merger expenses totaled $2.6 million for the year ended December 31, 2014, which largely related to professional and legal fees included in non-interest expense on the consolidated statements of income. Valley also recorded a $7.6 million charge within income tax expense for the fourth quarter of 2014 which mostly related to the effect of the 1st United acquisition on the valuation of our deferred tax assets.

Fair Value Disclosures [Abstract]
Fair Value Measurement of Assets and Liabilities	FAIR VALUE MEASUREMENT OF ASSETS AND LIABILITIES (Note 3) ASC Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 Unadjusted exchange quoted prices in active markets for identical assets or liabilities, or identical liabilities traded as assets that the reporting entity has the ability to access at the measurement date. Level 2 Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly (i.e., quoted prices on similar assets), for substantially the full term of the asset or liability. Level 3 Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Assets and Liabilities Measured at Fair Value on a Recurring Basis and Non-Recurring Basis The following tables present the assets and liabilities that are measured at fair value on a recurring and non-recurring basis by level within the fair value hierarchy as reported on the consolidated statements of financial condition at December 31, 2015 and 2014 . The assets presented under “non-recurring fair value measurements” in the table below are not measured at fair value on an ongoing basis but are subject to fair value adjustments under certain circumstances (e.g., when an impairment loss is recognized).

The changes in Level 3 assets measured at fair value on a recurring basis for the years ended December 31, 2015 , 2014 and 2013 are summarized below: Available For Sale Securities 2015 2014 2013 (in thousands) Balance, beginning of the period $ 19,309 $ 28,523 $ 71,674 Net (losses) gains included in other comprehensive income (1,072 ) 1,648 657 Sales (2,674 ) (7,718 ) (36,681 ) Settlements (1,770 ) (3,144 ) (7,127 ) Balance, end of the period $ 13,793 $ 19,309 $ 28,523 There was no change in unrealized gains or losses on Level 3 assets included in earnings during 2015 , 2014 and 2013 . Transfers into and out of Level 3 assets are generally made in response to a decrease or an increase, respectively, in the availability of observable market data used in the securities’ pricing obtained primarily through independent pricing services or dealer market participants. See further details regarding the valuation techniques used for the fair value measurement of the financial instruments below. There were no transfers of assets into and out of Level 3, or between Level 1 and Level 2 during 2015 and 2014 . There have been no material changes in the valuation methodologies used at December 31, 2015 from December 31, 2014 . Assets and Liabilities Measured at Fair Value on a Recurring Basis The following valuation techniques were used for financial instruments measured at fair value on a recurring basis. All of the valuation techniques described below apply to the unpaid principal balance excluding any accrued interest or dividends at the measurement date. Interest income and expense are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on acquired discount or premium. Available for sale and trading securities. All U.S. Treasury securities, certain corporate and other debt securities, and certain common and preferred equity securities (including certain trust preferred securities) are reported at fair values utilizing Level 1 inputs. The majority of other investment securities are reported at fair value utilizing Level 2 inputs. The prices for these instruments are obtained through an independent pricing service or dealer market participants with whom Valley has historically transacted both purchases and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviews the data and assumptions used in pricing the securities by its third party provider to ensure the highest level of significant inputs are derived from market observable data. For certain securities, the inputs used by either dealer market participants or an independent pricing service, may be derived from unobservable market information (Level 3 inputs). In these instances, Valley evaluates the appropriateness and quality of the assumption and the resulting price. In addition, Valley reviews the volume and level of activity for all available for sale and trading securities and attempts to identify transactions which may not be orderly or reflective of a significant level of activity and volume. For securities meeting these criteria, the quoted prices received from either market participants or an independent pricing service may be adjusted, as necessary, to estimate fair value and this results in fair values based on Level 3 inputs. In determining fair value, Valley utilizes unobservable inputs which reflect Valley’s own assumptions about the inputs that market participants would use in pricing each security. In developing its assertion of market participant assumptions, Valley utilizes the best information that is both reasonable and available without undue cost and effort. In calculating the fair value for the available for sale securities under Level 3, Valley prepared present value cash flow models for certain private label mortgage-backed securities. The cash flows for the residential mortgage-backed securities incorporated the expected cash flow of each security adjusted for default rates, loss severities and prepayments of the individual loans collateralizing the security. The following table presents quantitative information about Level 3 inputs used to measure the fair value of these securities at December 31, 2015 : Security Type Valuation Technique Unobservable Input Range Weighted Average Private label mortgage-backed securities Discounted cash flow Prepayment rate 0.1 - 22.2% 11.7 % Default rate 3.7 - 20.6 8.5 Loss severity 41.4 - 64.6 58.5 Significant increases or decreases in any of the unobservable inputs in the table above in isolation would result in a significantly lower or higher fair value measurement of the securities. Generally, a change in the assumption used for the default rate is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates. For the Level 3 available for sale private label mortgage-backed securities (consisting of 4 securities at December 31, 2015 and 5 securities at December 31, 2014 ), cash flow assumptions incorporated independent third party market participant data based on vintage year for each security. The discount rate utilized in determining the present value of cash flows for the mortgage-backed securities was arrived at by combining the yield on orderly transactions for similar maturity government sponsored mortgage-backed securities with (i) the historical average risk premium of similar structured private label securities, (ii) a risk premium reflecting current market conditions, including liquidity risk, and (iii) if applicable, a forecasted loss premium derived from the expected cash flows of each security. The estimated cash flows for each private label mortgage-backed security were then discounted at the aforementioned effective rate to determine the fair value. The quoted prices received from either market participants or independent pricing services are weighted with the internal price estimate to determine the fair value of each instrument. For the Level 3 available for sale pooled trust preferred securities (consisting of 1 security at December 31, 2015 and 2 securities at December 31, 2014 ), the resulting estimated future cash flows were discounted at a yield determined by reference to similarly structured securities for which observable orderly transactions occurred. The discount rate for each security was applied using a pricing matrix based on credit, security type and maturity characteristics to determine the fair value. The fair value calculation is received from an independent valuation adviser. In validating the fair value calculation from an independent valuation adviser, Valley reviews the accuracy of the inputs and the appropriateness of the unobservable inputs utilized in the valuation to ensure the fair value calculation is reasonable from a market participant perspective. Loans held for sale. The conforming residential mortgage loans originated for sale are reported at fair value using Level 2 inputs. The fair values were calculated utilizing quoted prices for similar assets in active markets. To determine these fair values, the mortgages held for sale are put into multiple tranches, or pools, based on the coupon rate and maturity of each mortgage. The market prices for each tranche are obtained from both Fannie Mae and Freddie Mac. The market prices represent a delivery price, which reflects the underlying price each institution would pay Valley for an immediate sale of an aggregate pool of mortgages. The market prices received from Fannie Mae and Freddie Mac are then averaged and interpolated or extrapolated, where required, to calculate the fair value of each tranche. Depending upon the time elapsed since the origination of each loan held for sale, non-performance risk and changes therein were addressed in the estimate of fair value based upon the delinquency data provided to both Fannie Mae and Freddie Mac for market pricing and changes in market credit spreads. Non-performance risk did not materially impact the fair value of mortgage loans held for sale at December 31, 2015 and 2014 based on the short duration these assets were held and the high credit quality of these loans. Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The fair value of Valley’s derivatives are determined using third party prices that are based on discounted cash flow analyses using observed market inputs, such as the LIBOR and Overnight Index Swap rate curves. The fair value of mortgage banking derivatives, consisting of interest rate lock commitments to fund residential mortgage loans and forward commitments for the future delivery of such loans (including certain loans held for sale at December 31, 2015 and 2014 ), is determined based on the current market prices for similar instruments provided by Freddie Mac and Fannie Mae. The fair values of most of the derivatives incorporate credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, to account for potential nonperformance risk of Valley and its counterparties. The credit valuation adjustments were not significant to the overall valuation of Valley’s derivatives at December 31, 2015 and 2014 . Assets and Liabilities Measured at Fair Value on a Non-recurring Basis The following valuation techniques were used for certain non-financial assets measured at fair value on a non-recurring basis, including non-performing loans held for sale carried at estimated fair value (less selling costs) when less than the unamortized cost, impaired loans reported at the fair value of the underlying collateral, loan servicing rights, other real estate owned and other repossessed assets (upon initial recognition or subsequent impairment) as described below. Non-performing loans held for sale. At December 31, 2014 , non-performing loans held for sale consisted of one commercial real estate loan that was transferred to the loans held for sale account during 2014 . At December 31, 2014, the loan was re-measured and reported at a fair value based on a non-binding sale agreement. The sale transaction was completed during the first quarter of 2015 . During 2014 , valuation write-downs charged to non-interest income related to this non-performing loan held for sale totaled $3.0 million . Impaired loans. Certain impaired loans are reported at the fair value of the underlying collateral if repayment is expected solely from the collateral and are commonly referred to as “collateral dependent impaired loans.” Collateral values are estimated using Level 3 inputs, consisting of individual appraisals that are significantly adjusted based on customized discounting criteria. At December 31, 2015 , appraisals were discounted up to 12 percent based on specific market data by location and property type. During 2015 and 2014 , collateral dependent impaired loans were individually re-measured and reported at fair value through direct loan charge-offs to the allowance for loan losses and/or a specific valuation allowance allocation based on the fair value of the underlying collateral. The collateral dependent loan charge-offs to the allowance for loan losses totaled $5.4 million and $6.5 million for the years ended December 31, 2015 and 2014 , respectively. These collateral dependent impaired loans with a total recorded investment of $15.8 million and $15.0 million at December 31, 2015 and 2014 , respectively, were reduced by specific valuation allowance allocations totaling $352 thousand and $1.0 million to a reported total net carrying amount of $15.4 million and $14.0 million at December 31, 2015 and 2014 , respectively. Loan servicing rights. Fair values for each risk-stratified group of loan servicing rights are calculated using a fair value model from a third party vendor that requires inputs that are both significant to the fair value measurement and unobservable (Level 3). The fair value model is based on various assumptions, including but not limited to, prepayment speeds, internal rate of return (“discount rate”), servicing cost, ancillary income, float rate, tax rate, and inflation. The prepayment speed and the discount rate are considered two of the most significant inputs in the model. At December 31, 2015 , the fair value model used prepayment speeds (stated as constant prepayment rates) from 0 percent up to 23 percent and a discount rate of 8 percent for the valuation of the loan servicing rights. A significant degree of judgment is involved in valuing the loan servicing rights using Level 3 inputs. The use of different assumptions could have a significant positive or negative effect on the fair value estimate. Impairment charges are recognized on loan servicing rights when the amortized cost of a risk-stratified group of loan servicing rights exceeds the estimated fair value. Valley recognized net recoveries of impairment charges on loan servicing rights totaling $303 thousand and net impairment charges totaling $88 thousand for the years ended December 31, 2015 and 2014 , respectively. Foreclosed assets. Certain foreclosed assets (consisting of other real estate owned and other repossessed assets), upon initial recognition and transfer from loans, are re-measured and reported at fair value through a charge-off to the allowance for loan losses based upon the fair value of the foreclosed assets. The fair value of a foreclosed asset, upon initial recognition, is typically estimated using Level 3 inputs, consisting of an appraisal that is adjusted based on customized discounting criteria, similar to the criteria used for impaired loans described above. The appraisals of foreclosed assets were discounted up to 7.6 percent at December 31, 2015 . During the years ended December 31, 2015 and 2014 , foreclosed assets measured at fair value upon initial recognition or subsequent re-measurement totaled $16.7 million and $18.1 million , respectively. The charge-offs of foreclosed assets to the allowance for loan losses totaled $1.6 million and $3.7 million for t he years ended December 31, 2015 and 2014 , respectively. The re-measurement of foreclosed assets at fair value subsequent to their initial recognition resulted in losses of $2.0 million and $4.7 million included in non-interest expense for the years ended December 31, 2015 and 2014 , respectively. Other Fair Value Disclosures ASC Topic 825, “Financial Instruments,” requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The fair value estimates presented in the following table were based on pertinent market data and relevant information on the financial instruments available as of the valuation date. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire portfolio of financial instruments. Because no market exists for a portion of the financial instruments, fair value estimates may be based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For instance, Valley has certain fee-generating business lines (e.g., its mortgage servicing operation, trust and investment management departments) that were not considered in these estimates since these activities are not financial instruments. In addition, the tax implications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of the estimates. The carrying amounts and estimated fair values of financial instruments not measured and not reported at fair value on the consolidated statements of financial condition at December 31, 2015 and 2014 were as follows: December 31, 2015 2014 Fair Value Hierarchy Carrying Amount Fair Value Carrying Amount Fair Value (in thousands) Financial assets Cash and due from banks Level 1 $ 243,575 $ 243,575 $ 462,569 $ 462,569 Interest bearing deposits with banks Level 1 170,225 170,225 367,838 367,838 Investment securities held to maturity: U.S. Treasury securities Level 1 138,978 149,483 139,121 151,300 U.S. government agency securities Level 2 12,859 13,130 14,081 14,385 Obligations of states and political subdivisions Level 2 504,865 527,263 500,018 519,693 Residential mortgage-backed securities Level 2 852,289 855,272 986,992 998,981 Trust preferred securities Level 2 59,785 46,437 98,456 86,243 Corporate and other debt securities Level 2 27,609 29,454 39,648 45,374 Total investment securities held to maturity 1,596,385 1,621,039 1,778,316 1,815,976 Net loans Level 3 15,936,929 15,824,475 13,371,560 13,085,830 Accrued interest receivable Level 1 63,554 63,554 57,333 57,333 Federal Reserve Bank and Federal Home Loan Bank stock (1) Level 1 145,068 145,068 133,117 133,117 Financial liabilities Deposits without stated maturities Level 1 13,095,647 13,095,647 11,291,646 11,291,648 Deposits with stated maturities Level 2 3,157,904 3,203,389 2,742,468 2,807,522 Short-term borrowings Level 1 1,076,991 1,076,991 146,781 146,781 Long-term borrowings Level 2 1,810,728 1,945,741 2,526,408 2,738,122 Junior subordinated debentures issued to capital trusts Level 2 41,414 44,127 41,252 44,584 Accrued interest payable (2) Level 1 13,110 13,110 15,526 15,526 (1) Included in other assets. (2) Included in accrued expenses and other liabilities. The following methods and assumptions were used to estimate the fair value of other financial assets and financial liabilities in the table above: Cash and due from banks and interest bearing deposits with banks. The carrying amount is considered to be a reasonable estimate of fair value because of the short maturity of these items. Investment securities held to maturity . Fair values are based on prices obtained through an independent pricing service or dealer market participants with whom Valley has historically transacted both purchases and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things (Level 2 inputs). Additionally, Valley reviews the volume and level of activity for all classes of held to maturity securities and attempts to identify transactions which may not be orderly or reflective of a significant level of activity and volume. For securities meeting these criteria, the quoted prices received from either market participants or an independent pricing service may be adjusted, as necessary. If applicable, the adjustment to fair value is derived based on present value cash flow model projections prepared by Valley utilizing assumptions similar to those incorporated by market participants. Loans . Fair values of loans are estimated by discounting the projected future cash flows using market discount rates that reflect the credit and interest-rate risk inherent in the loan. The discount rate is a product of both the applicable index and credit spread, subject to the estimated current new loan interest rates. The credit spread component is static for all maturities and may not necessarily reflect the value of estimating all actual cash flows repricing. Projected future cash flows are calculated based upon contractual maturity or call dates, projected repayments and prepayments of principal. Fair values estimated in this manner do not fully incorporate an exit-price approach to fair value, but instead are based on a comparison to current market rates for comparable loans. Accrued interest receivable and payable. The carrying amounts of accrued interest approximate their fair value due to the short-term nature of these items. Federal Reserve Bank and Federal Home Loan Bank stock. Federal Reserve Bank and FHLB stock are non-marketable equity securities and are reported at their redeemable carrying amounts, which approximate the fair value. Deposits. The carrying amounts of deposits without stated maturities (i.e., non-interest bearing, savings, NOW, and money market deposits) approximate their estimated fair value. The fair value of time deposits is based on the discounted value of contractual cash flows using estimated rates currently offered for alternative funding sources of similar remaining maturity. Short-term and long-term borrowings. The carrying amounts of certain short-term borrowings, including securities sold under agreement to repurchase (and from time to time, federal funds purchased and FHLB borrowings) approximate their fair values because they frequently re-price to a market rate. The fair values of other short-term and long-term borrowings are estimated by obtaining quoted market prices of the identical or similar financial instruments when available. When quoted prices are unavailable, the fair values of the borrowings are estimated by discounting the estimated future cash flows using current market discount rates of financial instruments with similar characteristics, terms and remaining maturity. Junior subordinated debentures issued to capital trusts. The fair value of debentures issued to capital trusts not carried at fair value is estimated utilizing the income approach, whereby the expected cash flows, over the remaining estimated life of the security, are discounted using Valley’s credit spread over the current yield on a similar maturity of U.S. Treasury security or the three-month LIBOR for the variable rate indexed debentures (Level 2 inputs). The credit spread used to discount the expected cash flows was calculated based on the median current spreads for all fixed and variable publicly traded trust preferred securities issued by banks.

Investment Securities	INVESTMENT SECURITIES (Note 4) Held to Maturity The amortized cost, gross unrealized gains and losses and fair value of investment securities held to maturity at December 31, 2015 and 2014 were as follows: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (in thousands) December 31, 2015 U.S. Treasury securities $ 138,978 $ 10,505 $ — $ 149,483 U.S. government agency securities 12,859 271 — 13,130 Obligations of states and political subdivisions: Obligations of states and state agencies 194,547 10,538 (10 ) 205,075 Municipal bonds 310,318 11,955 (85 ) 322,188 Total obligations of states and political subdivisions 504,865 22,493 (95 ) 527,263 Residential mortgage-backed securities 852,289 11,018 (8,035 ) 855,272 Trust preferred securities 59,785 36 (13,384 ) 46,437 Corporate and other debt securities 27,609 1,894 (49 ) 29,454 Total investment securities held to maturity $ 1,596,385 $ 46,217 $ (21,563 ) $ 1,621,039 December 31, 2014 U.S. Treasury securities $ 139,121 $ 12,179 $ — $ 151,300 U.S. government agency securities 14,081 304 — 14,385 Obligations of states and political subdivisions: Obligations of states and state agencies 197,440 9,410 (412 ) 206,438 Municipal bonds 302,578 10,955 (278 ) 313,255 Total obligations of states and political subdivisions 500,018 20,365 (690 ) 519,693 Residential mortgage-backed securities 986,992 18,233 (6,244 ) 998,981 Trust preferred securities 98,456 167 (12,380 ) 86,243 Corporate and other debt securities 39,648 5,726 — 45,374 Total investment securities held to maturity $ 1,778,316 $ 56,974 $ (19,314 ) $ 1,815,976 The age of unrealized losses and fair value of related securities held to maturity at December 31, 2015 and 2014 were as follows: Less than Twelve Months More than Twelve Months Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses (in thousands) December 31, 2015 Obligations of states and political subdivisions: Obligations of states and state agencies $ 6,837 $ (5 ) $ 1,965 $ (5 ) $ 8,802 $ (10 ) Municipal bonds 8,814 (72 ) 10,198 (13 ) 19,012 (85 ) Total obligations of states and political subdivisions 15,651 (77 ) 12,163 (18 ) 27,814 (95 ) Residential mortgage-backed securities 244,440 (2,916 ) 162,756 (5,119 ) 407,196 (8,035 ) Trust preferred securities — — 45,047 (13,384 ) 45,047 (13,384 ) Corporate and other debt securities 2,951 (49 ) — — 2,951 (49 ) Total $ 263,042 $ (3,042 ) $ 219,966 $ (18,521 ) $ 483,008 $ (21,563 ) December 31, 2014 Obligations of states and political subdivisions: Obligations of states and state agencies $ 4,927 $ (50 ) $ 19,050 $ (362 ) $ 23,977 $ (412 ) Municipal bonds — — 28,815 (278 ) 28,815 (278 ) Total obligations of states and political subdivisions 4,927 (50 ) 47,865 (640 ) 52,792 (690 ) Residential mortgage-backed securities 107,357 (563 ) 276,580 (5,681 ) 383,937 (6,244 ) Trust preferred securities — — 66,194 (12,380 ) 66,194 (12,380 ) Total $ 112,284 $ (613 ) $ 390,639 $ (18,701 ) $ 502,923 $ (19,314 ) The unrealized losses on investment securities held to maturity are primarily due to changes in interest rates (including, in certain cases, changes in credit spreads) and, in some cases, lack of liquidity in the marketplace. The total number of security positions in the securities held to maturity portfolio in an unrealized loss position at December 31, 2015 was 74 as compared to 57 at December 31, 2014 . The unrealized losses for the residential mortgage-backed securities category of the held to maturity portfolio at December 31, 2015 mostly related to investment grade securities issued by Fannie Mae. The unrealized losses for trust preferred securities at December 31, 2015 are all more than twelve months and primarily relate to four non-rated single-issuer securities, issued by bank holding companies. All single-issuer trust preferred securities classified as held to maturity are paying in accordance with their terms, have no deferrals of interest or defaults and, if applicable, the issuers meet the regulatory capital requirements to be considered “well-capitalized institutions” at December 31, 2015 . Management does not believe that any individual unrealized loss as of December 31, 2015 included in the table above represents other-than-temporary impairment as management mainly attributes the declines in fair value to changes in interest rates, widening credit spreads, and lack of liquidity in the market place, not credit quality or other factors. Based on a comparison of the present value of expected cash flows to the amortized cost, management believes there are no credit losses on these securities. Valley does not have the intent to sell, nor is it more likely than not that Valley will be required to sell, the securities contained in the table above before the recovery of their amortized cost basis or maturity. During the first quarter of 2015, Valley sold one corporate debt security classified as held to maturity with an amortized cost of $9.8 million . See "Realized Gains and Losses" section below for further details regarding this transaction. As of December 31, 2015 , the fair value of investments held to maturity that were pledged to secure public deposits, repurchase agreements, lines of credit, and for other purposes required by law was $943.5 million . The contractual maturities of investments in debt securities held to maturity at December 31, 2015 are set forth in the table below. Maturities may differ from contractual maturities in residential mortgage-backed securities because the mortgages underlying the securities may be prepaid without any penalties. Therefore, residential mortgage-backed securities are not included in the maturity categories in the following summary. December 31, 2015 Amortized Cost Fair Value (in thousands) Due in one year $ 77,803 $ 77,803 Due after one year through five years 145,649 154,897 Due after five years through ten years 314,175 332,505 Due after ten years 206,469 200,562 Residential mortgage-backed securities 852,289 855,272 Total investment securities held to maturity $ 1,596,385 $ 1,621,039 Actual maturities of debt securities may differ from those presented above since certain obligations provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty. The weighted-average remaining expected life for residential mortgage-backed securities held to maturity was 6.6 years at December 31, 2015 . Available for Sale The amortized cost, gross unrealized gains and losses and fair value of investment securities available for sale at December 31, 2015 and 2014 were as follows: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (in thousands) December 31, 2015 U.S. Treasury securities $ 551,173 $ 4 $ (1,704 ) $ 549,473 U.S. government agency securities 29,316 665 (18 ) 29,963 Obligations of states and political subdivisions: Obligations of states and state agencies 44,285 196 (67 ) 44,414 Municipal bonds 80,717 209 (374 ) 80,552 Total obligations of states and political subdivisions 125,002 405 (441 ) 124,966 Residential mortgage-backed securities 701,764 3,348 (8,684 ) 696,428 Trust preferred securities* 10,458 — (2,054 ) 8,404 Corporate and other debt securities 78,202 1,239 (1,889 ) 77,552 Equity securities 21,022 575 (1,522 ) 20,075 Total investment securities available for sale $ 1,516,937 $ 6,236 $ (16,312 ) $ 1,506,861 December 31, 2014 U.S. Treasury securities $ 51,063 $ 2 $ (1,622 ) $ 49,443 U.S. government agency securities 33,163 748 (86 ) 33,825 Obligations of states and political subdivisions: Obligations of states and state agencies 11,160 — (24 ) 11,136 Municipal bonds 33,340 127 (552 ) 32,915 Total obligations of states and political subdivisions 44,500 127 (576 ) 44,051 Residential mortgage-backed securities 643,382 5,854 (4,960 ) 644,276 Trust preferred securities* 23,194 296 (2,953 ) 20,537 Corporate and other debt securities 73,585 1,645 (1,218 ) 74,012 Equity securities 21,071 671 (916 ) 20,826 Total investment securities available for sale $ 889,958 $ 9,343 $ (12,331 ) $ 886,970 * Includes two and three pooled trust preferred securities, principally collateralized by securities issued by banks and insurance companies, at December 31, 2015 and 2014, respectively.

The total number of security positions in the securities available for sale portfolio in an unrealized loss position at December 31, 2015 was 291 as compared to 96 at December 31, 2014 . At December 31, 2015 the unrealized losses less than twelve months included larger number of small loss positions as compared to 2014. The unrealized losses within the residential mortgage-backed securities category of the available for sale portfolio at December 31, 2015 largely related to several investment grade residential mortgage-backed securities mainly issued by Ginnie Mae and Fannie Mae. The unrealized losses for trust preferred securities at December 31, 2015 in the more than twelve months category in the table above entirely relate to 2 pooled trust preferred securities with a combined amortized cost of $10.5 million and a fair value of $8.4 million . One of the two pooled trust preferred securities had a unrealized loss of $1.4 million and an investment grade rating at December 31, 2015 . The second pooled trust preferred security had a unrealized loss of $610 thousand , a non-investment grade rating and was initially other-than-temporarily impaired in 2008 with additional estimated credit losses recognized in 2009 and 2011. As of December 31, 2015 , the fair value of securities available for sale that were pledged to secure public deposits, repurchase agreements, lines of credit, and for other purposes required by law, was $489.8 million . The contractual maturities of investments securities available for sale at December 31, 2015 are set forth in the following table. Maturities may differ from contractual maturities in residential mortgage-backed securities because the mortgages underlying the securities may be prepaid without any penalties. Therefore, residential mortgage-backed securities are not included in the maturity categories in the following summary. December 31, 2015 Amortized Cost Fair Value (in thousands) Due in one year $ 501,717 $ 501,565 Due after one year through five years 89,821 89,834 Due after five years through ten years 120,691 118,331 Due after ten years 81,922 80,628 Residential mortgage-backed securities 701,764 696,428 Equity securities 21,022 20,075 Total investment securities available for sale $ 1,516,937 $ 1,506,861 Actual maturities of debt securities may differ from those presented above since certain obligations provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty. The weighted-average remaining expected life for residential mortgage-backed securities available for sale at December 31, 2015 was 8.5 years. Other-Than-Temporary Impairment Analysis Valley records impairment charges on its investment securities when the decline in fair value is considered other-than-temporary. Numerous factors, including lack of liquidity for re-sales of certain investment securities; decline in the creditworthiness of the issuer; absence of reliable pricing information for investment securities; adverse changes in business climate; adverse actions by regulators; prolonged decline in value of equity investments; or unanticipated changes in the competitive environment could have a negative effect on Valley’s investment portfolio and may result in other-than-temporary impairment on certain investment securities in future periods. Valley’s investment portfolios include private label mortgage-backed securities, trust preferred securities principally issued by bank holding companies (including two pooled trust preferred securities), corporate bonds, and perpetual preferred and common equity securities issued by banks. These investments may pose a higher risk of future impairment charges by Valley as a result of the unpredictable nature of the U.S. economy and its potential negative effect on the future performance of the security issuers and, if applicable, the underlying mortgage loan collateral of the security. For residential mortgage-backed securities, Valley estimates loss projections for each security by stressing the cash flows from the individual loans collateralizing the security using expected default rates, loss severities, and prepayment speeds, in conjunction with the underlying credit enhancement (if applicable) for each security. Based on collateral and origination vintage specific assumptions, a range of possible cash flows is identified to determine whether other-than-temporary impairment exists. For the single-issuer trust preferred securities and corporate and other debt securities, Valley reviews each portfolio to determine if all the securities are paying in accordance with their terms and have no deferrals of interest or defaults. A deferral event by a bank holding company for which Valley holds trust preferred securities may require the recognition of an other-than-temporary impairment charge if Valley determines that it is more likely than not that all contractual interest and principal cash flows may not be collected. Among other factors, the probability of the collection of all interest and principal determined by Valley in its impairment analysis declines if there is an increase in the estimated deferral period of the issuer. Additionally, a FDIC receivership for any single-issuer would result in an impairment and significant loss. Including the other factors outlined above, Valley analyzes the performance of the issuers on a quarterly basis, including a review of performance data from the issuers’ most recent bank regulatory report, if applicable, to assess their credit risk and the probability of impairment of the contractual cash flows of the applicable security. All of the issuers had capital ratios at December 31, 2015 that were at or above the minimum amounts to be considered a “well-capitalized” financial institution, if applicable, and/or have maintained performance levels adequate to support the contractual cash flows of the trust preferred securities. Management does not believe that any individual unrealized loss as of December 31, 2015 represents an other-than-temporary impairment, as management mainly attributes the declines in value to changes in interest rates and recent market volatility, not credit quality or other factors. Based on a comparison of the present value of expected cash flows to the amortized cost, management believes there are no credit losses on these securities. Valley has no intent to sell, nor is it more likely than not that Valley will be required to sell, the securities contained in the table above before the recovery of their amortized cost basis or, if necessary, maturity. At December 31, 2015, approximately 50 percent of the $629.8 million carrying value of obligations of states and political subdivisions were issued by the states of (or municipalities within) New Jersey, New York and Maryland. The obligations of states and political subdivisions mainly consist of general obligation bonds and, to much lesser extent, special revenue bonds which had an aggregated amortized cost and fair value of $17.6 million and $18.5 million , respectively, at December 31, 2015. The special revenue bonds were mainly issued by the Port Authorities of New York and New Jersey, as well as various school districts. As part of Valley’s pre-purchase analysis and on-going quarterly assessment of impairment of the obligations of states and political subdivisions, our Credit Risk Management Department conducts a financial analysis and risk rating assessment of each security issuer based on the issuer’s most recently issued financial statements and other publicly available information. Substantially all of these investments are investment grade. As of December 31, 2015, these securities are expected to perform in accordance with their contractual terms and, as a result, Valley expects to recover the entire amortized cost basis of these securities. For the two pooled trust preferred securities, Valley evaluates the projected cash flows from each of its tranches in the two securities to determine if they are adequate to support their future contractual principal and interest payments. Valley assesses the credit risk and probability of impairment of the contractual cash flows by projecting the default rates over the life of the security. Higher projected default rates will decrease the expected future cash flows from each security. If the projected decrease in cash flows affects the cash flows projected for the tranche held by Valley, the security would be considered to be other-than-temporarily impaired. The perpetual preferred securities, reported in equity securities, are hybrid investments that are assessed for impairment by Valley as if they were debt securities. Therefore, Valley assessed the creditworthiness of each security issuer, as well as any potential change in the anticipated cash flows of the securities as of December 31, 2015 . Based on this analysis, management believes the declines in fair value of these securities are attributable to a lack of liquidity in the marketplace and are not reflective of any deterioration in the creditworthiness of the issuers. Other-Than-Temporarily Impaired Securities There was no other-than-temporary impairment recognized in earnings as a result of Valley's impairment analysis of its securities during 2015 , 2014 and 2013 . At December 31, 2015 , four previously impaired private label mortgage-backed securities had a combined amortized cost of $11.9 million and fair value of $11.7 million , respectively, while one previously impaired pooled trust preferred security had an amortized cost of $2.8 million and fair value of $2.1 million , respectively. During the first quarter of 2015, one previously impaired pooled trust preferred security was sold for an immaterial gain. See the "Realized Gains and Losses" section below for additional information. The previously impaired trust preferred securities discussed above were not accruing interest during the years ended December 31, 2015 , 2014 , and 2013 . See Note 1 for details regarding Valley's policy for the recognition of interest on impaired debt securities. The following table presents the changes in the credit loss component of cumulative other-than-temporary impairment losses on debt securities classified as either held to maturity or available for sale that Valley has recognized in earnings, for which a portion of the impairment loss (non-credit factors) was recognized in other comprehensive income or loss for the years ended December 31, 2015 , 2014 and 2013 : 2015 2014 2013 (in thousands) Balance, beginning of period $ 8,947 $ 9,990 $ 33,290 Accretion of credit loss impairment due to an increase in expected cash flows (728 ) (661 ) (461 ) Sales (2,382 ) (382 ) (22,839 ) Balance, end of period $ 5,837 $ 8,947 $ 9,990 The credit loss component of the impairment loss represents the difference between the present value of expected future cash flows and the amortized cost basis of the security prior to considering credit losses. The beginning balance represents the credit loss component for debt securities for which other-than-temporary impairment occurred prior to each period presented. Other-than-temporary impairments recognized in earnings for credit impaired debt securities are presented as additions in two components based upon whether the current period is the first time the debt security was credit impaired (initial credit impairment) or is not the first time the debt security was credit impaired (subsequent credit impairment). The credit loss component is reduced if Valley sells, intends to sell or believes it will be required to sell previously credit impaired debt securities. Additionally, the credit loss component is reduced if (i) Valley receives cash flows in excess of what it expected to receive over the remaining life of the credit impaired debt security, (ii) the security matures or (iii) the security is fully written down. Realized Gains and Losses Gross gains (losses) realized on sales, maturities and other securities transactions included in earnings for the years ended December 31, 2015 , 2014 and 2013 were as follows: 2015 2014 2013 (in thousands) Sales transactions: Gross gains $ 3,274 $ 746 $ 14,098 Gross losses (947 ) (2 ) (44 ) $ 2,327 $ 744 $ 14,054 Maturities and other securities transactions: Gross gains $ 293 $ 10 $ 662 Gross losses (133 ) (9 ) (38 ) $ 160 $ 1 $ 624 Gains on securities transactions, net $ 2,487 $ 745 $ 14,678 Valley recognized gross gains from sales transactions of investment securities totaling $3.3 million for the year ended December 31, 2015 mostly due to the sale of corporate debt securities and trust preferred securities with amortized cost totaling $25.9 million . These transactions included a corporate debt security classified as held to maturity and a previously impaired pooled trust preferred security with amortized costs of $9.8 million and $2.6 million , respectively. Additionally, during 2015 Valley recognized $947 thousand of gross losses primarily due to the sale of mostly trust preferred securities with a total amortized cost of $8.3 million . The vast majority of the sales of investment securities were due to an investment portfolio re-balancing during the first quarter of 2015 due to changes in our regulatory capital calculation under the new Basel III regulatory capital reform (effective for Valley on January 1, 2015). Under ASC Topic 320, “Investments - Debt and Equity Securities,” the sale of held to maturity securities based upon the change in capital requirements is permitted without tainting the remaining held to maturity investment portfolio. The gross gains totaling $14.1 million for the year ended December 31, 2013 included a $10.7 million gain on sale of the previously impaired trust preferred securities issued by one deferring bank holding company. Trading Securities The fair value of trading securities (consisting of 2 single-issuer bank trust preferred securities) was $14.2 million at December 31, 2014 . During the first quarter of 2015, one of the two securities was redeemed by the issuer and the other security was sold prior to its issuer's call date in April 2015. Total net trading gains and losses (included in the other non-interest income category of the consolidated statements of income) were immaterial for the years ended December 31, 2015 , 2014 and 2013. Interest income on trading securities totaled $213 thousand , $1.2 million , and $1.8 million for the years ended December 31, 2015 , 2014 and 2013 , respectively.

Loans	LOANS (Note 5) The detail of the loan portfolio as of December 31, 2015 and 2014 was as follows: December 31, 2015 December 31, 2014 Non-PCI Loans PCI Loans* Total Non-PCI Loans PCI Loans* Total (in thousands) Loans: Commercial and industrial $ 2,156,549 $ 383,942 $ 2,540,491 $ 1,959,927 $ 291,184 $ 2,251,111 Commercial real estate: Commercial real estate 6,069,532 1,355,104 7,424,636 5,053,742 1,107,139 6,160,881 Construction 607,694 147,253 754,947 476,094 57,040 533,134 Total commercial real estate loans 6,677,226 1,502,357 8,179,583 5,529,836 1,164,179 6,694,015 Residential mortgage 2,912,079 218,462 3,130,541 2,419,044 157,328 2,576,372 Consumer: Home equity 391,809 119,394 511,203 400,136 97,111 497,247 Automobile 1,238,826 487 1,239,313 1,144,780 51 1,144,831 Other consumer 426,147 15,829 441,976 298,389 11,948 310,337 Total consumer loans 2,056,782 135,710 2,192,492 1,843,305 109,110 1,952,415 Total loans $ 13,802,636 $ 2,240,471 $ 16,043,107 $ 11,752,112 $ 1,721,801 $ 13,473,913 * PCI loans include covered loans (mostly consisting of commercial real estate and residential mortgage loans) totaling $122.3 million and $211.9 million at December 31, 2015 and 2014, respectively. Total non-PCI loans are net of unearned premiums and deferred loan costs totaling $3.5 million at December 31, 2015 as compared to net of unearned discounts and deferred loan fees of $9.0 million at December 31, 2014 . The outstanding balances (representing contractual balances owed to Valley) for PCI loans totaled $2.4 billion and $1.9 billion at December 31, 2015 and 2014 , respectively. During the first quarter of 2014, we elected to transfer certain non-performing loans totaling $35.6 million (before $8.3 million of loan charge-offs at the transfer date) from the non-covered loan portfolio (primarily within the commercial real estate loan and commercial and industrial loan categories) to loans held for sale. With the exception of one loan held for sale at December 31, 2015 , all of the transferred loans were sold during the second quarter of 2014. This sale transaction of the remaining loan was completed during the first quarter of 2015. There were no other sales or transfers of loans from the held for investment portfolio during 2015 and 2014 . Purchased Credit-Impaired Loans (Including Covered Loans) PCI loans are accounted for in accordance with ASC Subtopic 310-30 and are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance (i.e., the allowance for loan losses), and aggregated and accounted for as pools of loans based on common risk characteristics. The difference between the undiscounted cash flows expected at acquisition and the initial carrying amount (fair value) of the PCI loans, or the “accretable yield,” is recognized as interest income utilizing the level-yield method over the life of each pool. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “non-accretable difference,” are not recognized as a yield adjustment, as a loss accrual or a valuation allowance. Reclassifications of the non-accretable difference to the accretable yield may occur subsequent to the loan acquisition dates due to increases in expected cash flows of the loan pools. Valley's PCI loan portfolio included covered loans (i.e., loans in which the Bank will share losses with the FDIC under loss-sharing agreements) totaling $122.3 million and $211.9 million at December 31, 2015 and 2014 , respectively. See Note 1 for additional information. The following table presents information regarding the estimates of the contractually required payments, the cash flows expected to be collected, and the estimated fair value of the PCI loans acquired in the CNL acquisition (see Note 2), as of the December 1, 2015 closing date for the acquisition. (in thousands) Contractually required principal and interest $ 993,940 Contractual cash flows not expected to be collected (non-accretable difference) (41,545 ) Expected cash flows to be collected 952,395 Interest component of expected cash flows (accretable yield) (126,930 ) Fair value of acquired loans $ 825,465 The following table presents changes in the accretable yield for PCI loans for the years ended December 31, 2015 and 2014 : 2015 2014 (in thousands) Balance, beginning of period $ 336,208 $ 223,799 Acquisition 126,930 246,993 Accretion (105,078 ) (74,507 ) Net increase (decrease) in expected cash flows 57,119 (60,077 ) Balance, end of period $ 415,179 $ 336,208 The net increase (decrease) in expected cash flows for certain pools of loans (included in the table above) is recognized prospectively as an adjustment to the yield over the estimated remaining life of the individual pools. The net increase of $57.1 million during 2015 was largely due to an increase in the expected cash flows mostly driven by lower loss expectations for certain PCI loan pools due to reforecasted cash flows during the fourth quarter of 2015. Conversely, the net decrease of $60.1 million during 2014 was largely due to an increase in the expected repayment speeds for certain non-covered PCI loan pools during the second quarter of 2014. Based upon the reforecasted cash flows during the second quarter of 2014, the average expected life of the non-covered PCI loans decreased to 2.2 years from approximately 4 years last forecasted during the second quarter of 2013. FDIC Loss-Share Receivable The receivable arising from the loss-sharing agreements with the FDIC is measured separately from the covered loan portfolio because the agreements are not contractually part of the covered loans and are not transferable should the Bank choose to dispose of the covered loans. The FDIC loss share receivable (which is included in other assets on Valley's consolidated statements of financial condition) totaled $8.3 million and $13.8 million at December 31, 2015 and 2014 , respectively. The aggregate effects of changes in the FDIC loss-share receivable was a reduction in non-interest income of $3.3 million , $20.8 million and $8.4 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Related Party Loans In the ordinary course of business, Valley has granted loans to certain directors, executive officers and their affiliates (collectively referred to as “related parties”). These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other unaffiliated persons and do not involve more than normal risk of collectability. The following table summarizes the changes in the total amounts of loans and advances to the related parties during the year ended December 31, 2015 : 2015 (in thousands) Outstanding at beginning of year $ 234,278 New loans and advances 8,128 Repayments (50,840 ) Outstanding at end of year $ 191,566 All loans to related parties are performing as of December 31, 2015 . Loan Portfolio Risk Elements and Credit Risk Management Credit risk management. For all of its loan types discussed below, Valley adheres to a credit policy designed to minimize credit risk while generating the maximum income given the level of risk. Management reviews and approves these policies and procedures on a regular basis with subsequent approval by the Board of Directors annually. Credit authority relating to a significant dollar percentage of the overall portfolio is centralized and controlled by the Credit Risk Management Division and by the Credit Committee. A reporting system supplements the management review process by providing management with frequent reports concerning loan production, loan quality, concentrations of credit, loan delinquencies, non-performing, and potential problem loans. Loan portfolio diversification is an important factor utilized by Valley to manage its risk across business sectors and through cyclical economic circumstances. Commercial and industrial loans. A significant proportion of Valley’s commercial and industrial loan portfolio is granted to long standing customers of proven ability, strong repayment performance, and high character. Underwriting standards are designed to assess the borrower’s ability to generate recurring cash flow sufficient to meet the debt service requirements of loans granted. While such recurring cash flow serves as the primary source of repayment, a significant number of the loans are collateralized by borrower assets intended to serve as a secondary source of repayment should the need arise. Anticipated cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value, or in the case of loans secured by accounts receivable, the ability of the borrower to collect all amounts due from its customers. Short-term loans may be made on an unsecured basis based on a borrower’s financial strength and past performance. Whenever possible, Valley will obtain the personal guarantee of the borrower’s principals to mitigate the risk. Unsecured loans, when made, are generally granted to the Bank’s most credit worthy borrowers. Unsecured commercial and industrial loans totaled $386.6 million and $345.1 million at December 31, 2015 and 2014 , respectively. Commercial real estate loans . Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans. Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real property. Loans generally involve larger principal balances and longer repayment periods as compared to commercial and industrial loans. Repayment of most loans is dependent upon the cash flow generated from the property securing the loan or the business that occupies the property. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy and accordingly, conservative loan to value ratios are required at origination, as well as stress tested to evaluate the impact of market changes relating to key underwriting elements. The properties securing the commercial real estate portfolio represent diverse types, with most properties located within Valley’s primary markets. Construction loans . With respect to loans to developers and builders, Valley originates and manages construction loans structured on either a revolving or non-revolving basis, depending on the nature of the underlying development project. These loans are generally secured by the real estate to be developed and may also be secured by additional real estate to mitigate the risk. Non-revolving construction loans often involve the disbursement of substantially all committed funds with repayment substantially dependent on the successful completion and sale, or lease, of the project. Sources of repayment for these types of loans may be from pre-committed permanent loans from other lenders, sales of developed property, or an interim loan commitment from Valley until permanent financing is obtained elsewhere. Revolving construction loans (generally relating to single-family residential construction) are controlled with loan advances dependent upon the presale of housing units financed. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing. Residential mortgages. Valley originates residential, first mortgage loans based on underwriting standards that generally comply with Fannie Mae and/or Freddie Mac requirements. Appraisals and valuations of real estate collateral are contracted directly with independent appraisers or from valuation services and not through appraisal management companies. The Bank’s appraisal management policy and procedure is in accordance with regulatory requirements and guidance issued by the Bank’s primary regulator. Credit scoring, using FICO ® and other proprietary credit scoring models is employed in the ultimate, judgmental credit decision by Valley’s underwriting staff. Valley does not use third party contract underwriting services. Residential mortgage loans include fixed and variable interest rate loans secured by one to four family homes generally located in northern and central New Jersey, the New York City metropolitan area, Florida and eastern Pennsylvania. Valley’s ability to be repaid on such loans is closely linked to the economic and real estate market conditions in this region. In deciding whether to originate each residential mortgage, Valley considers the qualifications of the borrower as well as the value of the underlying property. Home equity loans. Home equity lending consists of both fixed and variable interest rate products. Valley mainly provides home equity loans to its residential mortgage customers within the footprint of its primary lending territory. Valley generally will not exceed a combined (i.e., first and second mortgage) loan-to-value ratio of 75 percent when originating a home equity loan. Automobile loans. Valley uses both judgmental and scoring systems in the credit decision process for automobile loans. Automobile originations (including light truck and sport utility vehicles) are largely produced via indirect channels, originated through approved automobile dealers. Automotive collateral is generally a depreciating asset and there are times in the life of an automobile loan where the amount owed on a vehicle may exceed its collateral value. Additionally, automobile charge-offs will vary based on the strength or weakness of the used vehicle market, original advance rate, when in the life cycle of a loan a default occurs and the condition of the collateral being liquidated. Where permitted by law, and subject to the limitations of the bankruptcy code, deficiency judgments are sought and acted upon to ultimately collect all money owed, even when a default resulted in a loss at collateral liquidation. Valley uses a third party to actively track collision and comprehensive risk insurance required of the borrower on the automobile and this third party provides coverage to Valley in the event of an uninsured collateral loss. Other consumer loans. Valley’s other consumer loan portfolio includes direct consumer term loans, both secured and unsecured. The other consumer loan portfolio includes exposures in personal lines of credit (including those secured by cash surrender value of life insurance), credit card loans and personal loans. Valley believes the aggregate risk exposure of these loans and lines of credit was not significant at December 31, 2015 . Unsecured consumer loans totaled approximately $18.8 million and $31.4 million , including $7.1 million and $7.6 million of credit card loans, at December 31, 2015 and 2014 , respectively.

Interest income recognized on a cash basis for loans classified as non-accrual totaled $1.3 million , $735 thousand and $1.3 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Impaired loans . Impaired loans, consisting of non-accrual commercial and industrial loans and commercial real estate loans over $250 thousand and all loans which were modified in troubled debt restructurings, are individually evaluated for impairment. PCI loans are not classified as impaired loans because they are accounted for on a pool basis.

From time to time, Valley may extend, restructure, or otherwise modify the terms of existing loans, on a case-by-case basis, to remain competitive and retain certain customers, as well as assist other customers who may be experiencing financial difficulties. If the borrower is experiencing financial difficulties and a concession has been made at the time of such modification, the loan is classified as a troubled debt restructured loan (TDR). Valley’s PCI loans are excluded from the TDR disclosures below because they are evaluated for impairment on a pool by pool basis. When an individual PCI loan within a pool is modified as a TDR, it is not removed from its pool. All TDRs are classified as impaired loans and are included in the impaired loan disclosures above. The majority of the concessions made for TDRs involve lowering the monthly payments on loans through either a reduction in interest rate below a market rate, an extension of the term of the loan without a corresponding adjustment to the risk premium reflected in the interest rate, or a combination of these two methods. The concessions rarely result in the forgiveness of principal or accrued interest. In addition, Valley frequently obtains additional collateral or guarantor support when modifying such loans. If the borrower has demonstrated performance under the previous terms and Valley’s underwriting process shows the borrower has the capacity to continue to perform under the restructured terms, the loan will continue to accrue interest. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. Performing TDRs (not reported as non-accrual loans) totaled $77.6 million and $97.7 million as of December 31, 2015 and 2014 , respectively. Non-performing TDRs totaled $21.0 million and $19.4 million as of December 31, 2015 and 2014 , respectively. The following table presents non-PCI loans by loan class modified as TDRs during the years ended December 31, 2015 and 2014 . The pre-modification and post-modification outstanding recorded investments disclosed in the table below represent the loan carrying amounts immediately prior to the modification and the carrying amounts at December 31, 2015 and 2014 , respectively.

These specific reserves are included in the allowance for loan losses for loans individually evaluated for impairment disclosed in Note 6. Partial loan charge-offs related to loans modified as TDRs presented in the table above totaled $320 thousand and $861 thousand during 2015 and 2014 , respectively. Additionally, two commercial loans totaling $6.1 million with one borrower that were modified as TDRs during 2014 were fully charged-off during 2014 . There were no full charge-offs resulting from loans modified as TDRs during 2015 . The non-PCI loans modified as TDRs within the previous 12 months and for which there was a payment default ( 90 or more days past due) consisted of four loans totaling $505 thousand at December 31, 2015 . Credit quality indicators . Valley utilizes an internal loan classification system as a means of reporting problem loans within commercial and industrial, commercial real estate, and construction loan portfolio classes. Under Valley’s internal risk rating system, loan relationships could be classified as “Pass”, “Special Mention”, “Substandard”, “Doubtful”, and “Loss.” Substandard loans include loans that exhibit well-defined weakness and are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, based on currently existing facts, conditions and values, highly questionable and improbable. Loans classified as Loss are those considered uncollectable with insignificant value and are charged-off immediately to the allowance for loan losses. Loans that do not currently pose a sufficient risk to warrant classification in one of the aforementioned categories, but pose weaknesses that deserve management’s close attention are deemed to be Special Mention. Loans rated as “Pass” loans do not currently pose any identified risk and can range from the highest to average quality, depending on the degree of potential risk. Risk ratings are updated any time the situation warrants. The following table presents the risk category of loans by class of loans (excluding PCI loans) based on the most recent analysis performed at December 31, 2015 and 2014 .

Receivables [Abstract]
Allowance for Credit Losses	ALLOWANCE FOR CREDIT LOSSES (Note 6) The allowance for credit losses consists of the allowance for loan losses and the allowance for unfunded letters of credit. Management maintains the allowance for credit losses at a level estimated to absorb probable loan losses of the loan portfolio and unfunded letter of credit commitments at the balance sheet date. The allowance for loan losses is based on ongoing evaluations of the probable estimated losses inherent in the loan portfolio, including unexpected additional credit impairment of PCI loan pools subsequent to acquisition. The following table summarizes the allowance for credit losses at December 31, 2015 and 2014 : December 31, 2015 2014 (in thousands) Components of allowance for credit losses: Allowance for loan losses $ 106,178 $ 102,353 Allowance for unfunded letters of credit 2,189 1,934 Total allowance for credit losses $ 108,367 $ 104,287 The following table summarizes the provision for credit losses for the years ended December 31, 2015 , 2014 and 2013 : 2015 2014 2013 (in thousands) Components of provision for credit losses: Provision for loan losses $ 7,846 $ 3,445 $ 14,895 Provision for unfunded letters of credit 255 (1,561 ) 1,200 Total provision for credit losses $ 8,101 $ 1,884 $ 16,095 The following table details the activity in the allowance for loan losses by portfolio segment for the years ended December 31, 2015 and 2014 : Commercial and Industrial Commercial Real Estate Residential Mortgage Consumer Unallocated Total (in thousands) December 31, 2015 Allowance for loan losses: Beginning balance $ 43,676 $ 42,840 $ 5,093 $ 5,179 $ 5,565 $ 102,353 Loans charged-off (1) (7,928 ) (2,790 ) (813 ) (3,441 ) — (14,972 ) Charged-off loans recovered (2) 7,233 1,759 421 1,538 — 10,951 Net charge-offs (695 ) (1,031 ) (392 ) (1,903 ) — (4,021 ) Provision for loan losses 5,786 6,197 (76 ) 1,504 (5,565 ) 7,846 Ending balance $ 48,767 $ 48,006 $ 4,625 $ 4,780 $ — $ 106,178 December 31, 2014 Allowance for loan losses: Beginning balance $ 51,551 $ 42,343 $ 7,786 $ 4,359 $ 7,578 $ 113,617 Loans charged-off (1)(3) (12,722 ) (9,470 ) (1,004 ) (3,702 ) — (26,898 ) Charged-off loans recovered (2) 6,874 3,110 248 1,957 — 12,189 Net charge-offs (5,848 ) (6,360 ) (756 ) (1,745 ) — (14,709 ) Provision for loan losses (2,027 ) 6,857 (1,937 ) 2,565 (2,013 ) 3,445 Ending balance $ 43,676 $ 42,840 $ 5,093 $ 5,179 $ 5,565 $ 102,353 (1) Includes covered loans charge-offs totaling $200 thousand and $1.5 million during 2015 and 2014 , respectively, primarily in the commercial and industrial loan and commercial real estate loan portfolios, respectively. (2) Includes covered loan recoveries totaling $462 thousand during 2014 . There were no covered loan recoveries during 2015. (3) The commercial and industrial loan and commercial real estate loan categories included $4.8 million and $4.0 million of charge-offs, respectively, related to the valuation of non-performing loans transferred to loans held for sale during 2014 . The following table represents the allocation of the allowance for loan losses and the related loans by loan portfolio segment disaggregated based on the impairment methodology for the years ended December 31, 2015 and 2014 . Loans individually evaluated for impairment represent Valley’s impaired loans. Loans acquired with discounts related to credit quality represent Valley’s PCI loans.

The enhancements were meant to increase the level of precision in the allowance for credit losses. As a result, Valley will no longer have an “unallocated” segment in its allowance for credit losses, as the risks and uncertainties meant to be captured by the unallocated allowance have been included in the qualitative framework for the respective loan portfolio segment (reported in the table above) at December 31, 2015. As such, the unallocated allowance has in essence been reallocated to the applicable portfolios based on the risks and uncertainties it was meant to capture. See Note 1 to the consolidated financial statements for additional information regarding our allowance for loan losses.

Debt Disclosure [Abstract]
Junior Subordinated Debentures Issued to Capital Trusts	JUNIOR SUBORDINATED DEBENTURES ISSUED TO CAPITAL TRUSTS (Note 11) Valley acquired GCB Capital Trust III, State Bancorp Capital Trust I, and State Bancorp Capital Trust II in past bank acquisitions. These statutory trusts were established for the sole purpose of issuing trust preferred securities and related trust common securities. The proceeds from such issuances were used by the trust to purchase an equivalent amount of junior subordinated debentures issued by the acquired bank, and now assumed by Valley. The junior subordinated debentures, the sole assets of the trusts, are unsecured obligations of Valley, and are subordinate and junior in right of payment to all present and future senior and subordinated indebtedness and certain other financial obligations of Valley. Valley does not consolidate its capital trusts based on U.S. GAAP but wholly owns all of the common securities of each trust. The table below summarizes the outstanding junior subordinated debentures and the related trust preferred securities issued by each trust as of December 31, 2015 : December 31, 2015 GCB Capital Trust III State Bancorp Capital Trust I State Bancorp Capital Trust II ($ in thousands) Junior Subordinated Debentures: Carrying value (1) $ 24,846 $ 8,624 $ 7,944 Contractual principal balance $ 24,743 $ 10,310 $ 10,310 Annual interest rate (2) 6.96 % 3-month LIBOR + 3.45% 3-month LIBOR + 2.85% Stated maturity date July 30, 2037 November 7, 2032 January 23, 2034 Initial call date July 30, 2017 November 7, 2007 January 23, 2009 Trust Preferred Securities: Face value $ 24,000 $ 10,000 $ 10,000 Annual distribution rate (2) 6.96 % 3-month LIBOR + 3.45% 3-month LIBOR + 2.85% Issuance date July 2, 2007 October 29, 2002 December 19, 2003 Distribution dates (3) Quarterly Quarterly Quarterly (1) The carrying value for GCB Capital Trust III includes an unamortized purchase accounting premium of $103 thousand , and the carrying values for State Bancorp Capital Trust I and State Bancorp Capital Trust II include purchase accounting discounts of $1.7 million and $2.4 million , respectively. (2) Interest on GCB Capital Trust III is fixed until July 30, 2017, then resets to 3 -month LIBOR plus 1.4 percent . The annual interest rate for all of the junior subordinated debentures and related trust preferred securities excludes the effect of the purchase accounting adjustments. (3) All cash distributions are cumulative. The junior subordinated debentures issued to GCB Capital Trust III, State Bancorp Capital Trust I and State Bancorp Capital Trust II had total carrying values of $24.9 million , $8.5 million and $7.8 million , respectively, and total contractual principal balances of $24.7 million , $10.3 million and $10.3 million , respectively, at December 31, 2014 . The trust preferred securities issued by GCB Capital Trust III, and State Bancorp Capital Trust I and State Bancorp Capital Trust II had total face values of $24.0 million , $10.0 million and $10.0 million , respectively, at December 31, 2014 . The trust preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the junior subordinated debentures at the stated maturity date or upon redemption on the date no earlier than the call dates noted in the table above. The trusts’ ability to pay amounts due on the trust preferred securities is solely dependent upon Valley making payments on the related junior subordinated debentures. Valley’s obligation under the junior subordinated debentures and other relevant trust agreements, in aggregate, constitutes a full and unconditional guarantee by Valley of the trusts’ obligations under the trust preferred securities issued. Under the junior subordinated debenture agreements, Valley has the right to defer payment of interest on the debentures and, therefore, distributions on the trust preferred securities, for up to five years , but not beyond the stated maturity dates in the table above. Currently, Valley has no intention to exercise its right to defer interest payments on the debentures. The trust preferred securities are included in Valley’s consolidated Tier 1 capital and total capital for regulatory purposes at December 31, 2015 . However, based upon the new final regulatory guidance, our Tier 1 capital treatment of the trust preferred securities issued by our capital trusts was 75 percent disallowed as of January 1, 2015 and will be fully phased out of Tier 1 capital on January 1, 2016.

Benefit Plans

Benefit Plans	12 Months Ended

Compensation and Retirement Disclosure [Abstract]
Benefit Plans	BENEFIT PLANS (Note 12) Pension Plan The Bank has a non-contributory defined benefit plan (qualified plan) covering most of its employees. The qualified plan benefits are based upon years of credited service and the employee’s highest average compensation as defined. Additionally, the Bank has a supplemental non-qualified, non-funded retirement plan, which is designed to supplement the pension plan for key officers, and Valley has a non-qualified, non-funded directors’ retirement plan (both of these plans are referred to as the “non-qualified plans” below). On June 19, 2013, the Board of Directors approved amendments to freeze the benefits earned under the qualified and non-qualified plans effective December 31, 2013. As a result, participants in each plan will not accrue further benefits and their pension benefits will be determined based on the compensation and service as of December 31, 2013. Plan benefits will not increase for any compensation or service earned after such date. However, participants’ benefits will continue to vest as long as they work for Valley. As a result of these actions, Valley re-measured the projected benefit obligation of the affected plans and the funded status of each plan at June 30, 2013. The freeze and re-measurement decreased the projected benefit obligations by $22.9 million and decreased accumulated other comprehensive loss, net of tax, by $19.9 million during the six months ended June 30, 2013. The decrease in the plan obligations was mainly due to an increase in the discount rate from December 31, 2012 and the curtailment of plan benefits. At June 30, 2013, Valley used a discount rate of 4.87 percent for the re-measurement of the pension benefit obligation as compared to 4.26 percent at December 31, 2012. The discount rate is based on our consistent methodology of determining our discount rate based on an established yield curve that incorporates a broad group of Aa3 or higher rated bonds with durations equal to the expected benefit payment streams required by each plan. The assumption for the expected rate of return on plan assets was 7.50 percent at June 30, 2013 and remained unchanged from December 31, 2012. Additionally, a curtailment loss totaling $750 thousand was recognized as a component of net periodic pension expense during the second quarter of 2013 due to the re-measurement and freeze of the plans. The following table sets forth the change in the projected benefit obligation, the change in fair value of plan assets and the funded status and amounts recognized in Valley’s consolidated financial statements for the qualified and non-qualified plans at December 31, 2015 and 2014 : 2015 2014 (in thousands) Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 176,339 $ 145,034 Interest cost 6,889 6,897 Actuarial (gain) loss (17,177 ) 28,749 Benefits paid (8,390 ) (4,341 ) Projected benefit obligation at end of year $ 157,661 $ 176,339 Change in fair value of plan assets: Fair value of plan assets at beginning of year $ 194,646 $ 184,910 Actual return on plan assets 2,875 13,813 Employer contributions 283 264 Benefits paid (8,390 ) (4,341 ) Fair value of plan assets at end of year* $ 189,414 $ 194,646 Funded status of the plan $ 31,753 $ 18,307 Asset recognized 31,753 18,307 Accumulated benefit obligation 157,661 176,339 * Includes accrued interest receivable of $607 thousand and $652 thousand as of December 31, 2015 and 2014 , respectively. Amounts recognized as a component of accumulated other comprehensive loss as of year-end that have not been recognized as a component of the net periodic pension expense for Valley’s qualified and non-qualified plans are presented in the following table. Valley expects to recognize approximately $290 thousand of the net actuarial loss reported in the following table as of December 31, 2015 as a component of net periodic pension expense during 2016 . 2015 2014 (in thousands) Net actuarial loss $ 36,271 $ 43,091 Deferred tax benefit (15,118 ) (18,031 ) Total $ 21,153 $ 25,060 The non-qualified plans had a projected benefit obligation, accumulated benefit obligation, and fair value of plan assets as follows: 2015 2014 (in thousands) Projected benefit obligation $ 17,411 $ 18,118 Accumulated benefit obligation 17,411 18,118 Fair value of plan assets — — In determining discount rate assumptions, management looks to current rates on fixed-income corporate debt securities that receive a rating of Aa3 or higher from Moody’s with durations equal to the expected benefit payments streams required of each plan. The weighted average discount rate used in determining the actuarial present value of benefit obligations for the qualified and non-qualified plans were 4.33 percent and 4.02 percent as of December 31, 2015 and 2014 , respectively. The net periodic pension income and expense for the qualified and non-qualified plans included the following components for the years ended December 31, 2015 , 2014 and 2013 : 2015 2014 2013 (in thousands) Service cost $ — $ — $ 7,104 Interest cost 6,889 6,897 6,645 Expected return on plan assets (14,023 ) (12,967 ) (12,015 ) Amortization of prior service cost — — 898 Amortization of net loss 790 226 1,970 Recognized loss due to curtailment — — 750 Total net periodic pension (income) expense $ (6,344 ) $ (5,844 ) $ 5,352 Other changes in the qualified and non-qualified plan assets and benefit obligations recognized in other comprehensive loss for the years ended December 31, 2015 and 2014 were as follows: 2015 2014 (in thousands) Net (gain) loss $ (6,030 ) $ 27,902 Amortization of actuarial loss (790 ) (226 ) Total recognized in other comprehensive income $ (6,820 ) $ 27,676 Total recognized in net periodic pension (income) expense and other comprehensive loss (before tax) $ (13,163 ) $ 21,833 The benefit payments, which reflect expected future service, as appropriate, expected to be paid in future years are presented in the following table: Year Amount (in thousands) 2016 $ 6,447 2017 6,818 2018 7,181 2019 7,654 2020 7,964 2021 to 2025 43,909 The weighted average discount rate, expected long-term rate of return on assets and rate of compensation increase used in determining Valley’s pension expense for the years ended December 31, 2015 , 2014 and 2013 were as follows: 2015 2014 2013 Discount rate* 4.02 % 4.89 % 4.26/4.87% Expected long-term return on plan assets 7.50 % 7.50 % 7.50 % Rate of compensation increase N/A N/A 2.75 % * The discount rate for 2013 increased from 4.26 percent to 4.87 percent due to the plans’ freeze and re-measurement at June 30, 2013. The expected rate of return on plan assets assumption is based on the concept that it is a long-term assumption independent of the current economic environment and changes would be made in the expected return only when long-term inflation expectations change, asset allocations change or when asset class returns are expected to change for the long-term. In accordance with Section 402 (c) of ERISA, the qualified plan’s investment managers are granted full discretion to buy, sell, invest and reinvest the portions of the portfolio assigned to them consistent with the Bank’s Pension Committee’s policy and guidelines. The target asset allocation set for the qualified plan are equity securities ranging from 25 percent to 65 percent and fixed income securities ranging from 35 percent to 75 percent . The absolute investment objective for the equity portion is to earn at least 7 percent cumulative annual real return, after adjustment by the Consumer Price Index (CPI), over rolling five -year periods, while the relative objective is to earn returns above the S&P 500 Index over rolling three -year periods. For the fixed income portion, the absolute objective is to earn at least a 3 percent cumulative annual real return, after adjustment by the CPI over rolling five -year periods with a relative objective of earning returns above the Merrill Lynch Intermediate Government/Corporate Index over rolling three -year periods. Cash equivalents will be invested in money market funds or in other high quality instruments approved by the Trustees of the qualified plan. The exposure of the plan assets of the qualified plan to a concentration of credit risk is limited by the Bank’s Pension Committee’s diversification of the investments into various investment options with multiple asset managers. The Pension Committee engages an investment management advisory firm that regularly monitors the performance of the asset managers and ensures they are within compliance of the policies adopted by the Trustees. If the risk profile and overall return of assets managed are not in line with the risk objectives or expected return benchmarks for the qualified plan, the advisory firm may recommend the termination of an asset manager to the Pension Committee. In general, the plan assets of the qualified plan are investment securities that are well-diversified in terms of industry, capitalization and asset class. The following table presents the qualified plan weighted-average asset allocations by asset category that are measured at fair value on a recurring basis by level within the fair value hierarchy under ASC Topic 820. Financial assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. See Note 3 for further details regarding the fair value hierarchy.

Equity securities, U.S. Treasury securities and cash and money market funds are valued at fair value in the table above utilizing exchange quoted prices in active markets for identical instruments (Level 1 inputs). Mutual funds are measured at their respective net asset values, which represents fair values of the securities held in the funds based on exchange quoted prices available in active markets (Level 1 inputs). Corporate bonds and U.S. government agency securities are reported at fair value utilizing Level 2 inputs. The prices for these investments are derived from market quotations and matrix pricing obtained through an independent pricing service. Such fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Based upon actuarial estimates, Valley does not expect to make any contributions to the qualified plan. Funding requirements for subsequent years are uncertain and will significantly depend on whether the plan’s actuary changes any assumptions used to calculate plan funding levels, the actual return on plan assets, changes in the employee groups covered by the plan, and any legislative or regulatory changes affecting plan funding requirements. For tax planning, financial planning, cash flow management or cost reduction purposes, Valley may increase, accelerate, decrease or delay contributions to the plan to the extent permitted by law. Other Non-Qualified Plans Valley maintains other non-qualified plans for former directors of banks acquired, as well as a non-qualified plan for former senior management of Merchants Bank of New York acquired in January of 2001. Valley did not merge these plans into its existing non-qualified plans. Collectively, at December 31, 2015 and 2014 , the remaining obligations under these plans were $3.4 million and $4.1 million , respectively, of which $1.6 million and $2.1 million , respectively, were funded by Valley. As of December 31, 2015 and 2014 , the entire obligations were included in other liabilities and $1.0 million (net of a $748 thousand tax benefit) and $1.2 million (net of a $882 thousand tax benefit), respectively, were recorded in accumulated other comprehensive loss. The $1.0 million in accumulated other comprehensive loss will be reclassified to expense on a straight-line basis over the remaining benefit periods of these non-qualified plans. Bonus Plan Valley National Bank and its subsidiaries may award cash incentive and merit bonuses to its officers and employees based upon a percentage of the covered employees’ compensation as determined by the achievement of certain performance objectives. Amounts charged to salary expense were $9.0 million , $6.8 million and $6.0 million during 2015 , 2014 and 2013 , respectively. Savings and Investment Plan Valley National Bank maintains a KSOP, which is defined as a 401(k) plan with an employee stock ownership feature. This plan covers eligible employees of the Bank and its subsidiaries and allows employees to contribute a percentage of their salary, with the Bank matching a certain percentage of the employee contribution in cash and invested in accordance with each participant’s investment elections. The Bank recorded $7.1 million , $6.0 million and $2.6 million in expense for contributions to the plan for the years ended December 31, 2015 , 2014 and 2013 , respectively. Effective January 1, 2014, Valley increased the benefits under the Bank’s 401(k) plan in an effort to offset a portion of the employee benefits no longer accruing under the qualified pension plan after December 31, 2013. At such date, Valley’s contributions increased to a dollar-for-dollar matching contribution of up to six percent of eligible compensation contributed by an employee each pay period. Stock-Based Compensation Valley currently has one active employee stock option plan, the 2009 Long-Term Stock Incentive Plan (the “Employee Stock Incentive Plan”), adopted by Valley’s Board of Directors on November 17, 2008 and approved by its shareholders on April 14, 2009. The Employee Stock Incentive Plan is administered by the Compensation and Human Resources Committee (the “Committee”) appointed by Valley’s Board of Directors. The Committee can grant awards to officers and key employees of Valley. The purpose of the Employee Stock Incentive Plan is to provide additional incentive to officers and key employees of Valley and its subsidiaries, whose substantial contributions are essential to the continued growth and success of Valley, and to attract and retain competent and dedicated officers and other key employees whose efforts will result in the continued and long-term growth of Valley’s business. Under the Employee Stock Incentive Plan, as amended, Valley may award shares to its employees for up to 7.4 million shares of common stock in the form of stock appreciation rights, incentive stock options, non-qualified stock options, restricted stock awards and restricted stock units (RSUs). As of December 31, 2015 , 2.2 million shares of common stock were available for issuance under the Employee Stock Incentive Plan. The essential features of each award are described in the award agreement relating to that award. The grant, exercise, vesting, settlement or payment of an award may be based upon the fair value of Valley’s common stock on the last sale price reported for Valley’s common stock on such date or the last sale price reported preceding such date, except for performance-based restricted stock and RSUs with a market condition. The grant date fair value of performance-based awards that vest based on a market condition is determined by a third party specialist using a Monte Carlo valuation model. The maximum term to exercise an incentive stock option is ten years from the date of grant and is subject to a vesting schedule. Valley recorded total stock-based compensation expense, primarily for restricted stock awards, totaling $8.8 million , $7.5 million and $6.0 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. The stock-based compensation expense for 2015 , 2014 and 2013 included $2.6 million , $3.9 million and $2.7 million , respectively, related to stock awards granted to retirement eligible employees and was immediately recognized. The fair values of all other stock awards are expensed over the shorter of the vesting or required service period. As of December 31, 2015 , the unrecognized amortization expense for all stock-based compensation totaled approximately $17.1 million and will be recognized over an average remaining vesting period of approximately 3 years. Restricted Stock. Restricted stock is awarded to key employees providing for the immediate award of our common stock subject to certain vesting and restrictions under the Employee Stock Incentive Plan. Compensation expense is measured based on the grant-date fair value of the shares. The following table sets forth the changes in restricted stock awards outstanding for the years ended December 31, 2015 , 2014 and 2013 : Restricted Stock Awards Outstanding 2015 2014 2013 Outstanding at beginning of year 2,574,616 1,709,312 1,492,060 Granted 886,427 1,488,960 479,541 Vested (559,958 ) (524,663 ) (217,305 ) Forfeited (145,947 ) (98,993 ) (44,984 ) Outstanding at end of year 2,755,138 2,574,616 1,709,312 The restricted stock awards granted in 2015 have vesting periods ranging from three to six years . The average grant date fair value of restricted stock awarded during the year ended December 31, 2015 was $10.09 per share. Included in the restricted shares granted (in the table above) during 2014, 240 thousand shares were performance-based awards made to certain executive officers. The performance-based awards vest based on the same performance measures for the RSU grants discussed further below. A portion of the performance-based awards vest after three years based on the cumulative performance of Valley during that time period with an opportunity for earlier vesting of a portion of the shares based on growth in tangible book value performance as specified in the agreement. During 2015, 50 thousand shares of the performance-based restricted stock awards vested, while the remaining awards were unvested and outstanding as of December 31, 2015. Restricted Stock Units . For the first time, Valley granted 313 thousand shares of performance-based RSUs to certain executive officers in 2015. The RSUs vest based on (i) growth in tangible book value per share plus dividends ( 75 percent of performance shares) and (ii) total shareholder return as compared to our peer group ( 25 percent of performance shares). The RSUs "cliff" vest after three years based on the cumulative performance of Valley during that time period. The RSUs earn dividend equivalents (equal to cash dividends paid on Valley's common share) over the applicable performance period. Dividend equivalents and accrued interest, per the terms of the agreements, are accumulated and paid to the grantee at the vesting date, or forfeited if the performance conditions are not met. The grant date fair value of the RSUs was $8.98 per share. Compensation costs related to RSUs totaled $2.3 million , and were included in total stock-based compensation expense for the year ended December 31, 2015 . Stock Options . The fair value of each option granted on the date of grant is estimated using a binomial option pricing model. The fair values are estimated using assumptions for dividend yield based on the annual dividend rate; the stock volatility, based on Valley’s historical and implied stock price volatility; the risk free interest rates, based on the U.S. Treasury constant maturity bonds, in effect on the actual grant dates, with a remaining term approximating the expected term of the options; and expected exercise term calculated based on Valley’s historical exercise experience. The following table summarizes stock options activity as of December 31, 2015 , 2014 and 2013 and changes during the years ended on those dates: 2015 2014 2013 Weighted Average Exercise Weighted Average Exercise Weighted Average Exercise Stock Options Shares Price Shares Price Shares Price Outstanding at beginning of year 1,828,591 $ 17 2,322,593 $ 17 2,860,081 $ 17 Granted 100,000 11 — — — — Forfeited or expired (545,226 ) 18 (494,002 ) 19 (537,488 ) 19 Outstanding at end of year 1,383,365 16 1,828,591 17 2,322,593 17 Exercisable at year-end 1,283,365 16 1,828,591 17 2,320,696 17 The following table summarizes information about stock options outstanding and exercisable at December 31, 2015 : Options Outstanding and Exercisable Range of Exercise Prices Number of Options Weighted Average Remaining Contractual Life in Years Weighted Average Exercise Price $10-14 148,315 4.8 $ 12 14-15 453,074 2.2 15 15-17 176,723 0.9 17 17-18 36,496 0.1 17 18-21 468,757 0.9 19 1,283,365 1.8 16 The aggregate intrinsic value of options outstanding and exercisable was immaterial at December 31, 2015. Director Restricted Stock Plan. The Director Restricted Stock Plan provides the non-employee members of the Board of Directors with the opportunity to forgo some or their entire annual cash retainer and meeting fees in exchange for shares of Valley restricted stock. On January 29, 2014, the Director Restricted Stock Plan was amended to provide that no additional fees may be exchanged for Valley’s restricted stock effective April 1, 2014. The Director Restricted Stock Plan will terminate after the restricted stock remaining under the plan as of April 1, 2014 vests and is delivered, or is forfeited pursuant to such plan. The following table sets forth the changes in director’s restricted stock awards outstanding for the years ended December 31, 2015 , 2014 and 2013: Restricted Stock Awards Outstanding 2015 2014 2013 Outstanding at beginning of year 98,086 121,792 117,147 Granted — — 26,828 Vested (17,969 ) (23,706 ) (21,963 ) Forfeited — — (220 ) Outstanding at end of year 80,117 98,086 121,792

Income Taxes	INCOME TAXES (Note 13) Income tax expense for the years ended December 31, 2015 , 2014 and 2013 consisted of the following: 2015 2014 2013 (in thousands) Current expense (benefit): Federal $ 7,978 $ 25,156 $ 13,203 State (493 ) (5,549 ) 3,447 7,485 19,607 16,650 Deferred expense: Federal and State 16,453 11,455 30,329 Total income tax expense $ 23,938 $ 31,062 $ 46,979 The tax effects of temporary differences that gave rise to the significant portions of the deferred tax assets and liabilities as of December 31, 2015 and 2014 are as follows: 2015 2014 (in thousands) Deferred tax assets: Allowance for loan losses $ 44,382 $ 42,574 Depreciation 15,661 15,082 Employee benefits 16,104 17,893 Investment securities, including other-than-temporary impairment losses 18,697 15,972 Net operating loss carryforwards 57,722 39,462 Purchase accounting 40,585 31,327 Other 21,310 18,138 Total deferred tax assets 214,461 180,448 Deferred tax liabilities: Pension plans 18,861 13,081 Other investments 15,720 14,662 Other 21,449 21,127 Total deferred tax liabilities 56,030 48,870 Net deferred tax asset (included in other assets) $ 158,431 $ 131,578 Valley's federal net operating loss carryforwards totaled approximately $86.5 million at December 31, 2015 and expire during the period from 2029 through 2034 and state net operating loss carryforwards totaled approximately $733.5 million at December 31, 2015 and expire during the period from 2016 through 2034. Based upon taxes paid and projections of future taxable income over the periods in which the net deferred tax assets are deductible, management believes that it is more likely than not that Valley will realize the benefits of these deductible differences and loss carryforwards. Reconciliation between the reported income tax expense and the amount computed by multiplying consolidated income before taxes by the statutory federal income tax rate of 35 percent for the years ended December 31, 2015 , 2014 and 2013 were as follows: 2015 2014 2013 (in thousands) Federal income tax at expected statutory rate $ 44,413 $ 51,532 $ 62,629 (Decrease) increase due to: Tax-exempt interest, net of interest incurred to carry tax-exempt securities (4,864 ) (4,406 ) (4,876 ) Bank owned life insurance (2,385 ) (2,237 ) (2,087 ) State income tax expense, net of federal tax effect 15,274 12,866 9,904 Tax credits from securities and other investments (28,988 ) (20,555 ) (17,408 ) Reduction in reserve for uncertainties — (6,971 ) (1,821 ) Other, net 488 833 638 Income tax expense $ 23,938 $ 31,062 $ 46,979 A reconciliation of Valley’s gross unrecognized tax benefits for 2015 , 2014 and 2013 are presented in the table below: 2015 2014 2013 (in thousands) Beginning balance $ 18,647 $ 30,713 $ 31,052 Additions based on tax positions related to prior years 1,245 1,408 1,482 Settlements with taxing authorities — (9,050 ) (1,216 ) Reductions due to expiration of statute of limitations — (4,424 ) (605 ) Ending balance $ 19,892 $ 18,647 $ 30,713 The entire balance of unrecognized tax benefits, if recognized, would favorably affect our effective income tax rate. It is reasonably possible that the liability for unrecognized tax benefits could increase or decrease in the next twelve months due to completion of tax authorities’ exams or the expiration of statutes of limitations. Management estimates that the liability for unrecognized tax benefits could decrease by $19.9 million within the next twelve months. Valley’s policy is to report interest and penalties, if any, related to unrecognized tax benefits in income tax expense. Valley has accrued approximately $5.2 million and $4.5 million of interest associated with Valley’s uncertain tax positions at December 31, 2015 and 2014 , respectively. Valley files income tax returns in the U.S. federal and various state jurisdictions. With few exceptions, Valley is no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2009. Valley is under examination by the IRS and also currently under routine examination by various state jurisdictions, and we expect the examinations to be completed within the next twelve months. Valley has considered, for all open audits, any potential adjustments in establishing our reserve for unrecognized tax benefits as of December 31, 2015 . TAX CREDIT INVESTMENTS (Note 14) Valley’s tax credit investments are primarily related to investments promoting qualified affordable housing projects, and other investments related to community development and renewable energy sources. Some of these tax-advantaged investments support Valley’s regulatory compliance with the Community Reinvestment Act. Valley’s investments in these entities generate a return primarily through the realization of federal income tax credits, and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. These tax credits and deductions are recognized as a reduction of income tax expense. Valley’s tax credit investments are carried in other assets on the consolidated statements of financial condition. Valley’s unfunded capital and other commitments related to the tax credit investments are carried in accrued expenses and other liabilities on the consolidated statements of financial condition. Valley recognizes amortization of tax credit investments, including impairment losses, within non-interest expense of the consolidated statements of income using the equity method of accounting. An impairment loss is recognized when the fair value of the tax credit investment is less than its carrying value. The following table presents the balances of Valley’s affordable housing tax credit investments, other tax credit investments, and related unfunded commitments at December 31, 2015 and 2014 : December 31, 2015 2014 (in thousands) Other Assets: Affordable housing tax credit investments, net $ 32,094 $ 36,009 Other tax credit investments, net 70,681 66,023 Total tax credit investments, net $ 102,775 $ 102,032 Other Liabilities: Unfunded affordable housing tax credit commitments $ 7,330 $ 8,800 Unfunded other tax credit commitments 12,545 418 Total unfunded tax credit commitments $ 19,875 $ 9,218 The following table presents other information relating to Valley’s affordable housing tax credit investments and other tax credit investments for the years ended December 31, 2015 , 2014 and 2013 : 2015 2014 2013 (in thousands) Components of Income Tax Expense: Affordable housing tax credits and other tax benefits $ 4,709 $ 5,296 $ 4,722 Other tax credit investment credits and tax benefits 23,877 14,357 12,285 Total reduction in income tax expense $ 28,586 $ 19,653 $ 17,007 Amortization of Tax Credit Investments: Affordable housing tax credit investment losses $ 2,594 $ 3,184 $ 1,755 Affordable housing tax credit investment impairment losses 1,321 3,211 913 Other tax credit investment losses 1,079 2,359 1,630 Other tax credit investment impairment losses 22,318 15,442 10,054 Total amortization of tax credit investments recorded in non-interest expense $ 27,312 $ 24,196 $ 14,352

Based upon taxes paid and projections of future taxable income over the periods in which the net deferred tax assets are deductible, management believes that it is more likely than not that Valley will realize the benefits of these deductible differences and loss carryforwards. Reconciliation between the reported income tax expense and the amount computed by multiplying consolidated income before taxes by the statutory federal income tax rate of 35 percent for the years ended December 31, 2015 , 2014 and 2013 were as follows: 2015 2014 2013 (in thousands) Federal income tax at expected statutory rate $ 44,413 $ 51,532 $ 62,629 (Decrease) increase due to: Tax-exempt interest, net of interest incurred to carry tax-exempt securities (4,864 ) (4,406 ) (4,876 ) Bank owned life insurance (2,385 ) (2,237 ) (2,087 ) State income tax expense, net of federal tax effect 15,274 12,866 9,904 Tax credits from securities and other investments (28,988 ) (20,555 ) (17,408 ) Reduction in reserve for uncertainties — (6,971 ) (1,821 ) Other, net 488 833 638 Income tax expense $ 23,938 $ 31,062 $ 46,979 A reconciliation of Valley’s gross unrecognized tax benefits for 2015 , 2014 and 2013 are presented in the table below: 2015 2014 2013 (in thousands) Beginning balance $ 18,647 $ 30,713 $ 31,052 Additions based on tax positions related to prior years 1,245 1,408 1,482 Settlements with taxing authorities — (9,050 ) (1,216 ) Reductions due to expiration of statute of limitations — (4,424 ) (605 ) Ending balance $ 19,892 $ 18,647 $ 30,713 The entire balance of unrecognized tax benefits, if recognized, would favorably affect our effective income tax rate. It is reasonably possible that the liability for unrecognized tax benefits could increase or decrease in the next twelve months due to completion of tax authorities’ exams or the expiration of statutes of limitations. Management estimates that the liability for unrecognized tax benefits could decrease by $19.9 million within the next twelve months. Valley’s policy is to report interest and penalties, if any, related to unrecognized tax benefits in income tax expense. Valley has accrued approximately $5.2 million and $4.5 million of interest associated with Valley’s uncertain tax positions at December 31, 2015 and 2014 , respectively. Valley files income tax returns in the U.S. federal and various state jurisdictions. With few exceptions, Valley is no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2009. Valley is under examination by the IRS and also currently under routine examination by various state jurisdictions, and we expect the examinations to be completed within the next twelve months. Valley has considered, for all open audits, any potential adjustments in establishing our reserve for unrecognized tax benefits as of December 31, 2015 . TAX CREDIT INVESTMENTS (Note 14) Valley’s tax credit investments are primarily related to investments promoting qualified affordable housing projects, and other investments related to community development and renewable energy sources. Some of these tax-advantaged investments support Valley’s regulatory compliance with the Community Reinvestment Act. Valley’s investments in these entities generate a return primarily through the realization of federal income tax credits, and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. These tax credits and deductions are recognized as a reduction of income tax expense. Valley’s tax credit investments are carried in other assets on the consolidated statements of financial condition. Valley’s unfunded capital and other commitments related to the tax credit investments are carried in accrued expenses and other liabilities on the consolidated statements of financial condition. Valley recognizes amortization of tax credit investments, including impairment losses, within non-interest expense of the consolidated statements of income using the equity method of accounting. An impairment loss is recognized when the fair value of the tax credit investment is less than its carrying value. The following table presents the balances of Valley’s affordable housing tax credit investments, other tax credit investments, and related unfunded commitments at December 31, 2015 and 2014 : December 31, 2015 2014 (in thousands) Other Assets: Affordable housing tax credit investments, net $ 32,094 $ 36,009 Other tax credit investments, net 70,681 66,023 Total tax credit investments, net $ 102,775 $ 102,032 Other Liabilities: Unfunded affordable housing tax credit commitments $ 7,330 $ 8,800 Unfunded other tax credit commitments 12,545 418 Total unfunded tax credit commitments $ 19,875 $ 9,218 The following table presents other information relating to Valley’s affordable housing tax credit investments and other tax credit investments for the years ended December 31, 2015 , 2014 and 2013 : 2015 2014 2013 (in thousands) Components of Income Tax Expense: Affordable housing tax credits and other tax benefits $ 4,709 $ 5,296 $ 4,722 Other tax credit investment credits and tax benefits 23,877 14,357 12,285 Total reduction in income tax expense $ 28,586 $ 19,653 $ 17,007 Amortization of Tax Credit Investments: Affordable housing tax credit investment losses $ 2,594 $ 3,184 $ 1,755 Affordable housing tax credit investment impairment losses 1,321 3,211 913 Other tax credit investment losses 1,079 2,359 1,630 Other tax credit investment impairment losses 22,318 15,442 10,054 Total amortization of tax credit investments recorded in non-interest expense $ 27,312 $ 24,196 $ 14,352

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES (Note 15) Lease Commitments Certain bank facilities are occupied under non-cancelable long-term operating leases, which expire at various dates through 2058. Certain lease agreements provide for renewal options and increases in rental payments based upon increases in the consumer price index or the lessors’ cost of operating the facility. Minimum aggregate lease payments for the remainder of the lease terms are as follows: Sublease Year Gross Rents Rents Net Rents (in thousands) 2016 $ 28,255 $ 2,534 $ 25,721 2017 27,051 2,527 24,524 2018 26,455 1,972 24,483 2019 25,851 1,799 24,052 2020 25,311 1,396 23,915 Thereafter 292,933 8,458 284,475 Total lease commitments $ 425,856 $ 18,686 $ 407,170 Net occupancy expense for years ended December 31, 2015 , 2014 , and 2013 included net rental expense of approximately $31.7 million , $21.2 million , and $19.9 million , respectively, net of rental income of $3.8 million , $3.1 million , and $3.3 million , respectively, for leased bank facilities. In December 2013, Valley terminated a 20 year branch operating lease related to a building sale-leaseback transaction entered into during 2007. As a result of the lease termination, Valley recognized a gain of $11.3 million within the net gains on sales of assets category of other non-interest income for the year ended December 31, 2013. The $11.3 million gain represented the outstanding deferred gain on the original building sale that would have been amortized to income over the remaining lease term. The negotiated lease termination penalty recognized in 2013 was immaterial. Financial Instruments With Off-balance Sheet Risk In the ordinary course of business in meeting the financial needs of its customers, Valley, through its subsidiary Valley National Bank, is a party to various financial instruments, which are not reflected in the consolidated financial statements. These financial instruments include standby and commercial letters of credit, unused portions of lines of credit and commitments to extend various types of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the consolidated financial statements. The commitment or contract amount of these instruments is an indicator of the Bank’s level of involvement in each type of instrument as well as the exposure to credit loss in the event of non-performance by the other party to the financial instrument. The Bank seeks to limit any exposure of credit loss by applying the same credit policies in making commitments, as it does for on-balance sheet lending facilities. The following table provides a summary of financial instruments with off-balance sheet risk at December 31, 2015 and 2014 : 2015 2014 (in thousands) Commitments under commercial loans and lines of credit $ 2,554,146 $ 2,290,048 Home equity and other revolving lines of credit 822,506 749,716 Outstanding commercial mortgage loan commitments 724,236 429,474 Standby letters of credit 198,253 194,562 Outstanding residential mortgage loan commitments 54,293 79,849 Commitments under unused lines of credit—credit card 50,532 54,128 Commercial letters of credit 4,249 5,618 Commitments to sell loans 41,860 27,932 Obligations to advance funds under commitments to extend credit, including commitments under unused lines of credit, are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have specified expiration dates, which may be extended upon request, or other termination clauses and generally require payment of a fee. These commitments do not necessarily represent future cash requirements as it is anticipated that many of these commitments will expire without being fully drawn upon. The Bank’s lending activity for outstanding loan commitments is primarily to customers within the states of New Jersey, New York, Florida and Pennsylvania. Standby letters of credit represent the guarantee by the Bank of the obligations or performance of the bank customer in the event of the default of payment or nonperformance to a third party beneficiary. Loan sale commitments represent contracts for the sale of residential mortgage loans to third parties in the ordinary course of the Bank’s business. These commitments require the Bank to deliver loans within a specific period to the third party. The risk to the Bank is its non-delivery of loans required by the commitment, which could lead to financial penalties. The Bank has not defaulted on its loan sale commitments. Derivative Instruments and Hedging Activities Valley is exposed to certain risks arising from both its business operations and economic conditions. Valley principally manages its exposure to a wide variety of business and operational risks through management of its core business activities. Valley manages economic risks, including interest rate and liquidity risks, primarily by managing the amount, sources, and duration of its assets and liabilities and, from time to time, the use of derivative financial instruments. Specifically, Valley enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Valley’s derivative financial instruments are used to manage differences in the amount, timing, and duration of Valley’s known or expected cash receipts and its known or expected cash payments related to assets and liabilities as outlined below. Cash Flow Hedges of Interest Rate Risk. Valley’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, Valley uses interest rate swaps and caps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the payment of either fixed or variable-rate amounts in exchange for the receipt of variable or fixed-rate amounts from a counterparty. Interest rate caps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. At December 31, 2015 , Valley had the following cash flow hedge derivatives: • Four interest rate swaps with a total notional amount of $300 million to hedge the changes in cash flows associated with prime-rate-indexed deposits, consisting of consumer and commercial money market deposit accounts. Two of the four swaps, totaling $200 million , expire in October 2016 and require Valley to pay fixed-rate amounts at approximately 4.73 percent , in exchange for the receipt of variable-rate payments at the prime rate. The other two swaps totaling $100 million require the payment by Valley of fixed-rate amounts at approximately 5.11 percent in exchange for the receipt of variable-rate payments at the prime rate and expire in July 2017 . • One interest rate cap with a total notional amount of $125 million with a strike rate of 7.44 percent and a maturity date of September 27, 2023 used to hedge the total change in cash flows associated with prime-rate indexed deposits, consisting of consumer and commercial money market deposit accounts, which have variable interest rates indexed to the prime rate. • Three forward starting interest rate swaps with a total notional amount of $300 million to hedge the changes in cash flows associated with certain brokered money market deposits. Starting in November 2015 , the interest rate swaps required Valley to pay fixed-rate amounts ranging from approximately 2.57 percent to 2.97 percent , in exchange for the receipt of variable-rate payments at the three-month LIBOR rate. The three swaps have expiration dates ranging from November 2018 to November 2020 . • Four forward starting interest rate swaps with a total notional amount of $182 million to hedge the changes in cash flows associated with borrowed funds. Starting in March and April 2016, the interest rate swaps required Valley to pay fixed-rate amounts ranging from approximately 2.51 percent to 2.88 percent , in exchange for the receipt of variable-rate payments at the three-month LIBOR rate. The four swaps have expiration dates ranging from March 2019 to September 2020. During the third quarter of 2013, Valley entered into a $65 million forward-settle interest rate swap to protect Valley against adverse fluctuations in interest rates by reducing its exposure to variability in cash flows related to interest payments on its subordinated notes issuance in September 2013. The forward-settle swap was cash settled to coincide with the date of the subordinated note issuance. The change in fair value of the forward-settle swap was recorded in accumulated other comprehensive loss and is amortized into interest expense over the life of the debt. Fair Value Hedges of Fixed Rate Assets and Liabilities. Valley is exposed to changes in the fair value of certain of its fixed rate assets or liabilities due to changes in benchmark interest rates based on one-month LIBOR. From time to time, Valley uses interest rate swaps to manage its exposure to changes in fair value. Interest rate swaps designated as fair value hedges involve the receipt of variable rate payments from a counterparty in exchange for Valley making fixed rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. Valley includes the gain or loss on the hedged items in the same income statement line item as the loss or gain on the related derivatives. At December 31, 2015 , Valley had the following fair value hedge derivatives: • One interest rate swap with a notional amount of approximately $8.2 million used to hedge the change in the fair value of a commercial loan. • One interest rate swap transaction with a notional amount of $125 million , maturing in September 2023, used to hedge the change in the fair value of Valley’s 5.125 percent subordinated notes issued in September 2013 . Non-designated Hedges. Derivatives not designated as hedges may be used to manage Valley’s exposure to interest rate movements or to provide service to customers but do not meet the requirements for hedge accounting under U.S. GAAP. Derivatives not designated as hedges are not entered into for speculative purposes. Under a program, Valley executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that Valley executes with a third party, such that Valley minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. During the second quarter of 2014, Valley issued $25 million of market linked certificates of deposit through a broker dealer. The rate paid on these hybrid instruments is based on a formula derived from the spread between the long and short ends of the constant maturity swap (CMS) rate curve. This type of instrument is referred to as a "steepener" since it derives its value from the slope of the CMS curve. Valley has determined that these hybrid instruments contain an embedded swap contract which has been bifurcated from the host contract. Valley entered into a swap (with a total notional amount of $25 million ) almost simultaneously with the deposit issuance where the receive rate on the swap mirrors the pay rate on the brokered deposits. The bifurcated derivative and the stand alone swap are both marked to market through other non-interest expense. Although these instruments do not meet the hedge accounting requirements, the change in fair value of both the bifurcated derivative and the stand alone swap tend to move in opposite directions with changes in the three-month LIBOR rate and, therefore, provide an effective economic hedge. Valley also regularly enters into mortgage banking derivatives which are non-designated hedges. These derivatives include interest rate lock commitments provided to customers to fund certain residential mortgage loans to be sold into the secondary market and forward commitments for the future delivery of such loans. Valley enters into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on Valley’s commitments to fund the loans as well as on its portfolio of mortgage loans held for sale. Amounts included in the consolidated statements of financial condition related to the fair value of Valley’s derivative financial instruments were as follows: December 31, 2015 December 31, 2014 Fair Value Fair Value Other Assets Other Liabilities Notional Amount Other Assets Other Liabilities Notional Amount (in thousands) Derivatives designated as hedging instruments: Cash flow hedge interest rate caps and swaps $ 1,284 $ 24,823 $ 907,000 $ 2,229 $ 19,302 $ 1,007,000 Fair value hedge interest rate swaps 7,658 1,306 133,209 6,257 1,482 133,406 Total derivatives designated as hedging instruments $ 8,942 $ 26,129 $ 1,040,209 $ 8,486 $ 20,784 $ 1,140,406 Derivatives not designated as hedging instruments: Interest rate swaps and embedded derivatives $ 24,628 $ 24,623 $ 654,134 $ 12,464 $ 12,455 $ 378,849 Mortgage banking derivatives 204 92 73,438 37 91 40,857 Total derivatives not designated as hedging instruments $ 24,832 $ 24,715 $ 727,572 $ 12,501 $ 12,546 $ 419,706 Gains (losses) included in the consolidated statements of income and in other comprehensive income (loss), on a pre-tax basis, related to interest rate derivatives designated as hedges of cash flows were as follows: 2015 2014 2013 (in thousands) Amount of loss reclassified from accumulated other comprehensive loss to interest expense $ (7,075 ) $ (6,663 ) $ (6,898 ) Amount of (loss) gain recognized in other comprehensive income (12,360 ) (20,910 ) 4,255 The net gains or losses related to cash flow hedge ineffectiveness were immaterial during the years ended December 31, 2015 , 2014 and 2013 . The accumulated net after-tax losses related to effective cash flow hedges included in accumulated other comprehensive loss were $17.6 million and $14.5 million at December 31, 2015 and 2014 , respectively. Amounts reported in accumulated other comprehensive loss related to cash flow interest rate derivatives are reclassified to interest expense as interest payments are made on the hedged variable interest rate liabilities. Valley estimates that $11.8 million will be reclassified as an increase to interest expense in 2016 . Gains (losses) included in the consolidated statements of income related to interest rate derivatives designated as hedges of fair value were as follows: 2015 2014 2013 (in thousands) Derivative—interest rate swaps: Interest income $ 176 $ (13 ) $ 728 Interest expense 1,400 9,380 (3,774 ) Hedged item—loans, deposits and long-term borrowings: Interest income $ (176 ) $ 13 $ (728 ) Interest expense (1,473 ) (9,449 ) 3,805 During the years ended December 31, 2015 , 2014 and 2013 , the amounts recognized in non-interest expense related to the ineffectiveness of fair value hedges were immaterial. Valley also recognized a net reduction to interest expense of $100 thousand and $584 thousand for the years ended December 31, 2014 and 2013 , respectively, related to Valley’s fair value hedges on brokered time deposits, which includes net settlements on the derivatives. The fair value hedges on brokered time deposits expired in March 2014. Net gains (losses) included in the consolidated statements of income related to derivative instruments not designated as hedging instruments were as follows: 2015 2014 2013 (in thousands) Non-designated hedge interest rate derivatives Other non-interest expense $ 158 $ (214 ) $ 128 Collateral Requirements and Credit Risk Related Contingency Features. By using derivatives, Valley is exposed to credit risk if counterparties to the derivative contracts do not perform as expected. Management attempts to minimize counterparty credit risk through credit approvals, limits, monitoring procedures and obtaining collateral where appropriate. Credit risk exposure associated with derivative contracts is managed at Valley in conjunction with Valley’s consolidated counterparty risk management process. Valley’s counterparties and the risk limits monitored by management are periodically reviewed and approved by the Board of Directors. Valley has agreements with its derivative counterparties providing that if Valley defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Valley could also be declared in default on its derivative counterparty agreements. Additionally, Valley has an agreement with several of its derivative counterparties that contains provisions that require Valley’s debt to maintain an investment grade credit rating from each of the major credit rating agencies from which it receives a credit rating. If Valley’s credit rating is reduced below investment grade or such rating is withdrawn or suspended, then the counterparty could terminate the derivative positions, and Valley would be required to settle its obligations under the agreements. As of December 31, 2015 , Valley was in compliance with all of the provisions of its derivative counterparty agreements. As of December 31, 2015 , the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $36.0 million . Valley has derivative counterparty agreements that require minimum collateral posting thresholds for certain counterparties. At December 31, 2015 , Valley had $53.0 million in collateral posted with its counterparties. Litigation In the normal course of business, Valley may be a party to various outstanding legal proceedings and claims. In the opinion of management, the financial condition, results of operations, and liquidity of Valley should not be materially affected by the outcome of such legal proceedings and claims.

Offsetting [Abstract]
Balance Sheet Offsetting	BALANCE SHEET OFFSETTING (Note 16) Certain financial instruments, including derivatives (consisting of interest rate caps and swaps) and repurchase agreements (accounted for as secured long-term borrowings), may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. Valley is party to master netting arrangements with its financial institution counterparties; however, Valley does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of cash or marketable investment securities, is posted by the counterparty with net liability positions in accordance with contract thresholds. Master repurchase agreements which include “right of set-off” provisions generally have a legally enforceable right to offset recognized amounts. In such cases, the collateral would be used to settle the fair value of the repurchase agreement should Valley be in default. The table below presents information about Valley’s financial instruments that are eligible for offset in the consolidated statements of financial condition as of December 31, 2015 and 2014 .

Regulatory and Capital Requirem

Regulatory and Capital Requirements	12 Months Ended

Banking and Thrift [Abstract]
Regulatory and Capital Requirements	REGULATORY AND CAPITAL REQUIREMENTS (Note 17) Valley’s primary source of cash is dividends from the Bank. Valley National Bank, a national banking association, is subject to certain restrictions on the amount of dividends that it may declare without prior regulatory approval. In addition, the dividends declared cannot be in excess of the amount which would cause the subsidiary bank to fall below the minimum required for capital adequacy purposes. Valley and Valley National Bank are subject to the regulatory capital requirements administered by the Federal Reserve Bank and the OCC. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct significant impact on Valley’s consolidated financial statements. Under capital adequacy guidelines Valley and Valley National Bank must meet specific capital guidelines that involve quantitative measures of Valley’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require Valley and Valley National Bank to maintain minimum amounts and ratios of common equity Tier 1 capital, total and Tier 1 capital to risk-weighted assets, and Tier 1 capital to average assets, as defined in the regulations. As of December 31, 2015 and 2014 , Valley exceeded all capital adequacy requirements to which it was subject (see tables below). On January 1, 2015, the final rules implementing the Basel Committee on Banking Supervision capital guidelines for banking organizations (Basel III) regulatory capital framework and related Dodd-Frank Act changes became effective for Valley. These rules supersede the federal banking agencies' general risk-based capital rules (Basel I). Full compliance with all of the final rule's requirements is phased in over a multi-year transition period ending on January 1, 2019. Basel III revised minimum capital requirements and adjusted prompt corrective action thresholds. Under the final rules, minimum requirements increased for both the quantity and quality of capital held by Valley and the Bank. The rules included a new common equity Tier 1 capital to risk-weighted assets ratio of 4.5 percent , raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0 percent to 6.0 percent , required a minimum ratio of total capital to risk-weighted assets of 8.0 percent , and required a minimum leverage ratio of 4.0 percent . A new capital conservation buffer, comprised of common equity Tier 1 capital, was also established above the regulatory minimum capital requirements. This conservation buffer will be phased in beginning January 1, 2016 at 0.625 percent of risk-weighted assets and increase each subsequent year by an additional 0.625 percent until reaching its final level of 2.5 percent of risk-weighted assets on January 1, 2019.

Equity [Abstract]
Common and Preferred Stock	COMMON AND PREFERRED STOCK (Note 18) Common Stock Dividend Reinvestment Plan. Effective June 29, 2009, Valley may issue up to 10.0 million authorized and previously unissued or treasury shares of Valley common stock for purchases under Valley’s dividend reinvestment plan (DRIP). Under the DRIP, a shareholder may choose to have future cash dividends automatically invested in Valley common stock and make voluntary optional cash payments of up to $100 thousand per quarter to purchase shares of Valley common stock. Shares purchased under this plan will be issued directly from Valley or in open market transactions. During 2015 , 2014 and 2013 , 713 thousand , 499 thousand , and 775 thousand of common shares, respectively, were reissued from treasury stock or issued from authorized common shares under the DRIP for net proceeds totaling $7.0 million , $5.0 million and $7.6 million , respectively. Common Stock Warrants. On January 1, 2012, Valley assumed in the acquisition of State Bancorp, Inc. a warrant issued (in connection with State Bancorp's redeemed preferred stock issuance) to the U.S. Treasury in December 2008. The ten -year warrant to purchase up to 489 thousand of Valley common shares has an exercise price of $11.30 per share, and is exercisable on a net exercise basis. During May 2015, the U.S. Treasury sold the warrant shares individually through a public action, in which Valley did not receive any of the proceeds. All of the warrants, which will expire on December 5, 2018, remained outstanding and unexercised at December 31, 2015 . In connection with the issuance of senior preferred shares in 2008 under the TARP program, Valley issued to the U.S. Treasury a ten-year warrant to purchase up to approximately $2.5 million of Valley common shares. During 2010, the U.S. Treasury sold the warrant shares individually through a public auction, in which Valley did not receive any of the proceeds. The warrants are currently traded on the New York Stock Exchange under the ticker symbol “VLY WS”. Each warrant entitles the holder to purchase approximately 1.103 Valley common shares at $16.12 per share and is exercisable through the expiration date of November 14, 2018. In July 2008, Valley issued approximately 918 thousand warrants as part of the purchase price for the acquisition of Greater Community Bancorp. All of these warrants expired unexercised on June 30, 2015, and are no longer outstanding. Repurchase Plan. In 2007, Valley’s Board of Directors approved the repurchase of up to $4.7 million of common shares. Purchases of Valley’s common shares may be made from time to time in the open market or in privately negotiated transactions generally not exceeding prevailing market prices. Repurchased shares are held in treasury and are expected to be used for general corporate purposes or issued under the dividend reinvestment plan. Under the repurchase plan, Valley made no purchases of its outstanding shares during the years ended December 31, 2015 , 2014 and 2013 . Other Stock Repurchases. Valley also purchases shares directly from its employees in connection with employee elections to withhold taxes related to the vesting of stock awards, including vested stock options exchanged for Valley common stock in the CNL acquisition. During the years ended December 31, 2015 , 2014 and 2013 , Valley purchased approximately 387 thousand , 174 thousand and 78 thousand shares, respectively, of its outstanding common stock at an average price of $9.95 , $9.96 and $9.91 , respectively, for such purpose. Preferred Stock On June 19, 2015, Valley issued 4.6 million shares of its Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series A, no par value per share, with a liquidation preference of $25 per share. Dividends on the preferred stock accrue and are payable quarterly in arrears, at a fixed rate per annum equal to 6.25 percent from the original issue date to, but excluding, June 30, 2025, and thereafter at a floating rate per annum equal to three-month LIBOR plus a spread of 3.85 percent . The net proceeds from the preferred stock offering totaled approximately $111.6 million . The preferred stock is included in Valley's Tier 1 capital and total risk-based capital at December 31, 2015.

Business Segments

Business Segments	12 Months Ended

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS (Note 22) Valley has four business segments that it monitors and reports on to manage Valley’s business operations. These segments are consumer lending, commercial lending, investment management, and corporate and other adjustments. Valley’s reportable segments have been determined based upon its internal structure of operations and lines of business. Each business segment is reviewed routinely for its asset growth, contribution to income before income taxes and return on average interest earning assets and impairment (if events or circumstances indicate a possible inability to realize the carrying amount). Expenses related to the branch network, all other components of retail banking, along with the back office departments of our subsidiary bank are allocated from the corporate and other adjustments segment to each of the other three business segments. Interest expense and internal transfer expense (for general corporate expenses) are allocated to each business segment utilizing a “pool funding” methodology, which involves the allocation of uniform funding cost based on each segments’ average earning assets outstanding for the period. The financial reporting for each segment contains allocations and reporting in line with Valley’s operations, which may not necessarily be comparable to any other financial institution. The accounting for each segment includes internal accounting policies designed to measure consistent and reasonable financial reporting, and may result in income and expense measurements that differ from amounts under U.S. GAAP. Furthermore, changes in management structure or allocation methodologies and procedures may result in changes in reported segment financial data. The consumer lending segment is mainly comprised of residential mortgages, home equity loans and automobile loans. The duration of the residential mortgage loan portfolio is subject to movements in the market level of interest rates and forecasted prepayment speeds. The average weighted life of the automobile loans within the portfolio is relatively unaffected by movements in the market level of interest rates. However, the average life may be impacted by new loans as a result of the availability of credit within the automobile marketplace and consumer demand for purchasing new or used automobiles. Consumer lending segment also includes the Wealth Management Division, comprised of trust, asset management, insurance services, and asset-based lending support services. The commercial lending segment is mainly comprised of floating rate and adjustable rate commercial and industrial loans, as well as fixed rate owner occupied and commercial real estate loans. Due to the portfolio’s interest rate characteristics, commercial lending is Valley’s business segment that is most sensitive to movements in market interest rates. The investment management segment generates a large portion of Valley’s income through investments in various types of securities. These securities are mainly comprised of fixed rate investments and depending on our liquid cash position, federal funds sold and interest-bearing deposits with banks (primarily the Federal Reserve Bank of New York), as part of our asset/liability management strategies. The fixed rate investments are one of Valley’s assets that are least sensitive assets to immediate changes in market interest rates. However, a portion of the investment portfolio is invested in shorter-duration securities to maintain the overall asset sensitivity of Valley’s balance sheet. Net gains and losses on the change in fair value of trading securities and net impairment losses on securities, if incurred, are reflected in the corporate and other adjustments segment. The amounts disclosed as “corporate and other adjustments” represent income and expense items not directly attributable to a specific segment, including net trading and securities gains and losses, and net impairment losses on securities not reported in the investment management segment above, interest expense related to the junior subordinated debentures issued to capital trusts, the change in fair value of Valley’s j unior subordinated debentures carried at fair value, interest expense related to subordinated notes, as well as income and expen se from derivative financial instruments.

Accounting Policies [Abstract]
Business	Business Valley National Bancorp, a New Jersey Corporation (Valley), is a bank holding company whose principal wholly-owned subsidiary is Valley National Bank (the “Bank”), a national banking association providing a full range of commercial, retail and trust and investment services through its branch and ATM network throughout northern and central New Jersey, the New York City boroughs of Manhattan, Brooklyn, Queens, Long Island, and southeast and central Florida. The Bank also lends to borrowers outside its branch network. The Bank is subject to intense competition from other financial services companies and is subject to the regulation of certain federal and state agencies and undergoes periodic examinations by certain regulatory authorities. Valley National Bank’s subsidiaries are all included in the consolidated financial statements of Valley. These subsidiaries include: • an all-line insurance agency offering property and casualty, life and health insurance; • asset management advisers which are Securities and Exchange Commission (SEC) registered investment advisors; • title insurance agencies in New Jersey, New York and Florida; • subsidiaries which hold, maintain and manage investment assets for the Bank; • a subsidiary which owns and services auto loans; • a subsidiary which specializes in health care equipment lending and other commercial equipment leases; • a subsidiary which owns and services general aviation aircraft loans and existing commercial equipment leases; and • a subsidiary which owns and services New York commercial loans. The Bank’s subsidiaries also include real estate investment trust subsidiaries (the “REIT” subsidiaries) which own real estate related investments and a REIT subsidiary which owns some of the real estate utilized by the Bank and related real estate investments. Except for Valley’s REIT subsidiaries, all subsidiaries mentioned above are directly or indirectly wholly-owned by the Bank. Because each REIT subsidiary must have 100 or more shareholders to qualify as a REIT, each REIT subsidiary has issued less than 20 percent of its outstanding non-voting preferred stock to individuals, most of whom are non-senior management Bank employees. The Bank owns the remaining preferred stock and all the common stock of the REITs.
Basis of Presentation	Basis of Presentation The consolidated financial statements of Valley include the accounts of its commercial bank subsidiary, Valley National Bank and all of Valley’s direct or indirect wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated. The accounting and reporting policies of Valley conform to U.S. generally accepted accounting principles (U.S. GAAP) and general practices within the financial services industry. In accordance with applicable accounting standards, Valley does not consolidate statutory trusts established for the sole purpose of issuing trust preferred securities and related trust common securities. See Note 11 for more details. Certain prior period amounts have been reclassified to conform to the current presentation. In preparing the consolidated financial statements in conformity with U.S. GAAP, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated statements of financial condition and results of operations for the periods indicated. Material estimates that are particularly susceptible to change are: the allowance for loan losses; the evaluation of goodwill and other intangible assets, and investment securities for impairment; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates. The current economic environment has increased the degree of uncertainty inherent in these material estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits in other banks (including the Federal Reserve Bank of New York) and, from time to time, overnight federal funds sold. The Bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank based on a percentage of deposits.
Investment Securities	Investment Securities At the time of purchase, management elects to classify investment securities into one of three categories: held to maturity, available for sale or trading. Investment securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold to maturity. Investment securities to be held for indefinite periods are classified as available for sale and carried at fair value, with unrealized holding gains and losses reported as a component of other comprehensive income or loss, net of tax. Securities that may be sold and reinvested over short durations as part of management’s asset/liability management strategies are classified as trading and are carried at fair value, with changes in unrealized holding gains and losses included in non-interest income in the accompanying consolidated statements of income as a component of net trading gains. Realized gains or losses on the sale of available for sale and trading securities are recognized by the specific identification method and are included in net gains on securities transactions and other non-interest income, respectively. Investments in Federal Home Loan Bank and Federal Reserve Bank stock, which have limited marketability, are carried at cost in other assets. Quarterly, Valley evaluates its investment securities classified as held to maturity and available for sale for other-than-temporary impairment. Other-than-temporary impairment means Valley believes the security’s impairment is due to factors that could include the issuer’s inability to pay interest or dividends, the potential for default, and/or other factors. When a held to maturity or available for sale debt security is assessed for other-than-temporary impairment, Valley has to first consider (a) whether it intends to sell the security, and (b) whether it is more likely than not that Valley will be required to sell the security prior to recovery of its amortized cost basis. If neither of these circumstances applies to a security, but Valley does not expect to recover the entire amortized cost basis, an other-than-temporary impairment loss has occurred that must be separated into two categories: (a) the amount related to credit loss, and (b) the amount related to other factors. In assessing the level of other-than-temporary impairment attributable to credit loss, Valley compares the present value of cash flows expected to be collected with the amortized cost basis of the security. The portion of the total other-than-temporary impairment related to credit loss is recognized in earnings, while the portion related to other factors is recognized in other comprehensive income or loss. The total other-than-temporary impairment loss is presented in the statement of income, less the portion recognized in other comprehensive income or loss. When a debt security becomes other-than-temporarily impaired, its amortized cost basis is reduced to reflect the portion of the total impairment related to credit loss. There was no other-than-temporary impairment recognized in earnings as a result of Valley's impairment analysis of its securities during 2015 , 2014 and 2013 . To determine whether a security’s impairment is other-than-temporary, Valley considers factors that include, among others, the causes of the decline in fair value, such as credit problems, interest rate fluctuations, or market volatility; the severity and duration of the decline; Valley’s ability and intent to hold equity security investments until they recover in value (as well as the likelihood of such a recovery in the near term); Valley’s intent to sell security investments; and whether it is more likely than not that Valley will be required to sell such securities before recovery of their individual amortized cost basis. For debt securities, the primary consideration in determining whether impairment is other-than-temporary is whether or not it is probable that current and/or future contractual cash flows have been or may be impaired. See the “Other-Than-Temporary Impairment Analysis” section of Note 4 for further discussion. Interest income on investments includes amortization of purchase premiums and discounts. Realized gains and losses are derived based on the amortized cost of the security sold. Valley discontinues the recognition of interest on debt securities if the securities meet both of the following criteria: (i) regularly scheduled interest payments have not been paid or have been deferred by the issuer, and (ii) full collection of all contractual principal and interest payments is not deemed to be the most likely outcome, resulting in the recognition of other-than-temporary impairment of the security.
Loans Held for Sale	Loans Held for Sale Loans held for sale generally consist of conforming residential mortgage loans originated and intended for sale in the secondary market and are carried at their estimated fair value on an instrument-by-instrument basis as permitted by the fair value option election under U.S. GAAP. Changes in fair value are recognized in non-interest income in the accompanying consolidated statements of income as a component of net gains on sales of loans. Origination fees and costs related to loans held for sale are recognized as earned and as incurred. Loans held for sale are generally sold with loan servicing rights retained by Valley. Gains recognized on loan sales include the value assigned to the rights to service the loan. See “Loan Servicing Rights” section below. From time to time, Valley may elect to transfer non-performing loans from commercial and industrial or commercial real estate portfolios.
Loans and Loan Fees	Loans and Loan Fees Loans are reported at their outstanding principal balance net of any unearned income, charge-offs, unamortized deferred fees and costs on originated loans and premium or discounts on purchased loans, except for purchased credit-impaired loans. Loan origination and commitment fees, net of related costs are deferred and amortized as an adjustment of loan yield over the estimated life of the loans approximating the effective interest method. Loans are deemed to be past due when the contractually required principal and interest payments have not been received as they become due. Loans are placed on non-accrual status generally, when they become 90 days past due and the full and timely collection of principal and interest becomes uncertain. When a loan is placed on non-accrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current income. Payments received on nonaccrual loans are generally applied against principal. A loan in which the borrowers’ obligation has not been released in bankruptcy courts may be restored to an accruing basis when it becomes well secured and is in the process of collection, or all past due amounts become current under the loan agreement and collectability is no longer doubtful.
Purchased Credit-Impaired Loans (Including Covered Loans)	Purchased Credit-Impaired Loans (Including Covered Loans) Purchased credit-impaired (PCI) loans are loans acquired at a discount (that is due, in part, to credit quality). Valley's PCI loan portfolio primarily consists of loans acquired in business combinations subsequent to 2011 and (covered) loans in which the Bank will share losses with the FDIC under loss-sharing agreements that have resulted from past FDIC-assisted transactions by Valley and 1st United acquired in 2014. The PCI loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no allowance for loan losses. Beginning in 2010, Valley has accounted for interest income on all loans acquired at a discount (that is due, in part, to credit quality) based on the acquired loans’ expected cash flows. The PCI loans may be aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. A pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flow. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income utilizing the level-yield method over the life of each pool. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or an allowance for loan losses. Increases in expected cash flows subsequent to the acquisition are recognized prospectively through adjustment of the yield on the pool over its remaining life, while decreases in expected cash flows are recognized as impairment through a loss provision and an increase in the allowance for loan losses. Therefore, the allowance for loan losses on these impaired pools reflect only losses incurred after the acquisition (representing the present value of all cash flows that were expected at acquisition but currently are not expected to be received). Any allowance for loan losses related to covered PCI loans is determined without consideration of the amounts recoverable through the FDIC loss-share agreements (see “FDIC Loss-Share Receivable” below). Valley had no allowance reserves related to PCI loans at December 31, 2015 as compared to $200 thousand (all related to covered PCI loans) at December 31, 2014. The Bank periodically evaluates the remaining contractual required payments due and estimates of cash flows expected to be collected for the underlying loans of each PCI loan pool. These evaluations, performed quarterly, require the continued use of key assumptions and estimates, similar to the initial estimate of fair value. Changes in the contractual required payments due and estimated cash flows expected to be collected may result in changes in the accretable yield and non-accretable difference or reclassifications between accretable yield and the non-accretable difference. For the pools with better than expected cash flows, the forecasted increase is recorded as an additional accretable yield that is recognized as a prospective increase to our interest income on loans and the FDIC loss-share receivable, if applicable, is prospectively reduced by the guaranteed portion of the additional cash flows expected to be received, with a corresponding reduction to non-interest income. See Note 5 for additional information. PCI loans that may have been classified as non-performing loans by an acquired bank are no longer classified as non-performing because these loans are accounted for on a pooled basis. Management’s judgment is required in classifying loans in pools as performing loans, and is dependent on having a reasonable expectation about the timing and amount of the pool cash flows to be collected, even if certain loans within the pool are contractually past due.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses (the “allowance”) is increased through provisions charged against current earnings and additionally by crediting amounts of recoveries received, if any, on previously charged-off loans. The allowance is reduced by charge-offs on loans or unfunded letters of credit which are determined to be a loss, in accordance with established policies, when all efforts of collection have been exhausted. The allowance is maintained at a level estimated to absorb probable credit losses inherent in the loan portfolio as well as other credit risk related charge-offs. The allowance is based on ongoing evaluations of the probable estimated losses inherent in the non-PCI loan portfolio and off-balance sheet unfunded letters of credit, as well as reserves for impairment of PCI loans subsequent to their acquisition date. As discussed under the “Purchased Credit-Impaired Loans” section above, the allowance for credit losses at December 31, 2014 included reserves for impairment of covered PCI loans subsequent to their acquisition date that were reduced to zero at December 31, 2015 through loan charge-offs recognized during 2015. The Bank’s methodology for evaluating the appropriateness of the allowance includes grouping the non-covered loan portfolio into loan segments based on common risk characteristics, tracking the historical levels of classified loans and delinquencies, estimating the appropriate loss look-back and loss emergence periods related to historical losses for each loan segment, providing specific reserves on impaired loans, and assigning incremental reserves where necessary based upon qualitative and economic outlook factors including numerous variables, such as the nature and trends of recent loan charge-offs. Additionally, the volume of non-performing loans, concentration risks by size, type, and geography, new markets, collateral adequacy, credit policies and procedures, staffing, underwriting consistency, loan review and economic conditions are taken into consideration. The allowance for loan losses consists of four elements: (i) specific reserves for individually impaired credits, (ii) reserves for adversely classified, or higher risk rated, loans that are not impaired, (iii) reserves for other loans based on historical loss factors (using the appropriate loss look-back and loss emergence periods) adjusted for both internal and external qualitative risk factors to Valley, including the aforementioned factors, as well as changes in both organic and purchased loan portfolio volumes, the composition and concentrations of credit, new market initiatives, and the impact of competition on loan structuring and pricing, and (iv) an allowance for PCI loan pools impaired subsequent to the acquisition date, if applicable. The Credit Risk Management Department individually evaluates non-accrual (non-homogeneous) commercial and industrial loans and commercial real estate loans over $250 thousand and all troubled debt restructured loans. The value of an impaired loan is measured based upon the underlying anticipated method of payment consisting of either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral, if the loan is collateral dependent, and its payment is expected solely based on the underlying collateral. If the value of an impaired loan is less than its carrying amount, impairment is recognized through a provision to the allowance for loan losses. Collateral dependent impaired loan balances are written down to the estimated current fair value (less estimated selling costs) of each loan’s underlying collateral resulting in an immediate charge-off to the allowance, excluding any consideration for personal guarantees that may be pursued in the Bank’s collection process. If repayment is based upon future expected cash flows, the present value of the expected future cash flows discounted at the loan’s original effective interest rate is compared to the carrying value of the loan, and any shortfall is recorded as a specific valuation allowance in the allowance for loan losses. Accrual of interest is discontinued on an impaired loan when management believes, after considering collection efforts and other factors, the borrower’s financial condition is such that collection of interest is doubtful. Cash collections on impaired loans are generally credited to the loan balance, and no interest income is recognized on these loans until the principal balance has been determined to be fully collectible. Residential mortgage loans and consumer loans usually consist of smaller balance homogeneous loans that are collectively evaluated for impairment, and are specifically excluded from the impaired loan portfolio, except where the loan is classified as a troubled debt restructured loan. The allowances established for probable losses on specific loans are based on a regular analysis and evaluation of the loans. Loans are evaluated based on an internal credit risk rating system for the commercial and industrial loan and commercial real estate loan portfolio segments and non-performing loan status for the residential and consumer loan portfolio segments. Loans are risk-rated based on an internal credit risk grading process that evaluates, among other things: (i) the obligor’s ability to repay; (ii) the underlying collateral, if any; and (iii) the economic environment and industry in which the borrower operates. This analysis is performed at the relationship manager level for all commercial and industrial loans and commercial real estate loans, and evaluated by the Loan Review Department on a test basis. Loans with a grade that is below “Pass” grade are adversely classified. See Note 5 for details. Any change in the credit risk grade of performing and/or non-performing loans affects the amount of the related allowance. Once a loan is adversely classified, the assigned relationship manager and/or a special assets officer in conjunction with the Credit Risk Management Department analyze the loan to determine whether the loan is impaired and, if impaired, the need to specifically allocate a portion of the allowance for loan losses to the loan. Specific valuation allowances are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things. Loans identified as losses by management are charged-off. Commercial loans are generally assessed for full or partial charge-off to the net realizable value for collateral dependent loans when a loan is between 90 or 120 days past due or sooner if it is probable that a loan may not be fully collectable. Residential loans and home equity loans are generally charged-off to net realizable value when the loan is 120 days past due (or sooner when the borrowers’ obligation has been released in bankruptcy). Automobile loans are fully charged-off when the loan is 120 days past due or partially charged-off to the net realizable value of collateral, if the collateral is recovered prior to such time. Unsecured consumer loans are generally fully charged-off when the loan is 150 days past due. The allowance allocations for other loans (i.e.; risk rated loans that are not adversely classified and loans that are not risk rated) are calculated by applying historical loss factors for each loan portfolio segment to the applicable outstanding loan portfolio balances. Loss factors are calculated using statistical analysis supplemented by management judgment. The statistical analysis considers historical default rates, historical loss severity in the event of default, and the average loss emergence period for each loan portfolio segment. The management analysis includes an evaluation of loan portfolio volumes, the composition and concentrations of credit, credit quality and current delinquency trends. Prior to December 31, 2015, the allowance also contains reserves to cover inherent losses within each of Valley’s loan portfolio segments, which have not been otherwise reviewed or measured on an individual basis. Such reserves include management’s evaluation of loan portfolio volumes, the composition and concentrations of credit, as well as other trends within the loan portfolio. These reserves reflected management’s attempt to ensure that the overall allowance reflected a margin for imprecision and the uncertainty that is inherent in estimates of probable incurred credit losses. As part of an ongoing evaluation process of developing the allowance for credit losses estimate, management continually evaluates and updates their assumptions based on the current economic environment and their own loss experience. During the fourth quarter of 2015, Valley refined and enhanced its assessment of the adequacy of the allowance for loan losses by extending the loss look-back period on the majority of its loan portfolios from three years to four years in order to capture more of the current economic cycle as it continues. Valley also enhanced its qualitative factor framework to capture the risks of several factors, including, but not limited to, the impact of changes in capitalization rates on collateral values, concentrations of certain loan types, including multi-family and exculpated loans, the volume of loans purchased from and serviced by third parties, as well as the rate of growth in Valley's real estate portfolios. These enhancements are meant to increase the level of precision in the allowance for credit losses. As a result, Valley will no longer have an “unallocated” segment in its allowance for credit losses, as the risks and uncertainties meant to be captured by the unallocated allowance have been included in the qualitative framework for the respective portfolios at December 31, 2015. As such, the unallocated allowance has in essence been reallocated to the certain portfolios based on the risks and uncertainties it was meant to capture. See Notes 5 and 6 for Valley’s loan credit quality and additional allowance disclosures.
Premises and Equipment, Net	Premises and Equipment, Net Premises and equipment are stated at cost less accumulated depreciation computed using the straight-line method over the estimated useful lives of the related assets. Generally, these useful lives range from three to forty years. Leasehold improvements are amortized over the term of the lease or estimated useful life of the asset, whichever is shorter. Major improvements are capitalized, while repairs and maintenance costs are charged to operations as incurred. Upon retirement or disposition, any gain or loss is credited or charged to operations.
Bank Owned Life Insurance	Bank Owned Life Insurance Valley owns bank owned life insurance (BOLI) to help offset the cost of employee benefits. BOLI is recorded at its cash surrender value. Valley’s BOLI is invested primarily in U.S. Treasury securities and residential mortgage-backed securities issued by government sponsored enterprises and Ginnie Mae. The majority of the underlying investment portfolio is managed by one independent investment firm. The change in the cash surrender value is included as a component of non-interest income and is exempt from federal and state income taxes as long as the policies are held until the death of the insured individuals.
Other Real Estate Owned	Other Real Estate Owned Valley acquires other real estate owned (OREO) through foreclosure on loans secured by real estate. OREO is reported at the lower of cost or fair value, as established by a current appraisal (less estimated costs to sell), and is included in other assets. Any write-downs at the date of foreclosure are charged to the allowance for loan losses. Expenses incurred to maintain these properties, unrealized losses resulting from valuation write-downs after the date of foreclosure, and realized gains and losses upon sale of the properties are included in other non-interest expense.
FDIC Loss-Share Receivable	FDIC Loss-Share Receivable Valley National Bank has several loss-share agreements with the FDIC (referred to as the “FDIC loss-share receivable” reported within other assets on Valley’s consolidated statements of financial condition) which relate to the LibertyPointe Bank and The Park Avenue Bank transactions entered into by Valley in 2010, as well as three prior FDIC-assisted transactions by 1st United (including Republic Federal Bank, The Bank of Miami and Old Harbor Bank) acquired by Valley in 2014. The FDIC loss-share receivable arising from the loss-share agreements is measured separately from the covered loan pools because the agreements are not contractually part of the covered loans and are not transferable should the Bank choose to dispose of the covered loans. At the date of acquisition, the FDIC loss-share receivable was measured at its fair value based on expected future cash flows covered by the loss share agreements. In addition, the asset is based on the credit adjustments estimated for each loan pool and the loss-share percentages. At December 31, 2015 and 2014, our FDIC loss-share receivable totaled $8.3 million and $13.8 million , respectively. Although this asset represents a contractual receivable from the FDIC, there is no contractual interest rate associated with the asset. The difference between the present value and the undiscounted cash flow expected to be collected from the FDIC is accreted into non-interest income over the life of the FDIC loss-share receivable. Actual or expected losses in excess of the acquisition date estimates result in an increase in the FDIC loss-share receivable. Conversely, when actual or expected losses are less than the acquisition date estimates, the loss share receivable is decreased. This reduction is recognized prospectively over the shorter of (i) the estimated life of the respective pools of covered loans or (ii) the term of the loss-sharing agreements with the FDIC. The FDIC loss-share receivable is also reduced and increased as loss-sharing payments are received from and made to the FDIC. Effective January 1, 2015, the losses on commercial related loans (commercial and industrial loans and commercial real estate loans) from the Republic Federal Bank transaction ceased being covered under the loss-share agreement. Any recoveries, net of expenses, of losses incurred prior to January 1, 2015 on such loans will continue to be covered (and must be shared with the FDIC in accordance with the loss-share agreement) through December 31, 2017. The losses on consumer related loans (residential mortgage loans and consumer loans) continue to be covered under the loss-share agreement through December 31, 2019. Under the terms of this loss-sharing agreement with the FDIC, losses are shared on the acquired loan and other real estate owned portfolio between 80 percent and 95 percent based upon certain aggregate loss limits. Effective April 1, 2015, the losses on commercial related loans from the LibertyPointe Bank and The Park Avenue Bank transactions ceased to be covered under the loss-share agreements. Any recoveries, net of expenses, of losses incurred prior to April 1, 2015 on such loans will continue to be covered by the loss-sharing agreement through March 31, 2018. The losses on consumer related loans will continue to be covered under the loss-share agreements through March 31, 2020. Under the terms of the loss-sharing agreements for the LibertyPointe Bank and The Park Avenue Bank transaction, the FDIC is obligated to reimburse Valley for 80.0 percent and 95.0 percent , respectively, of any future losses on covered consumer loans up to certain aggregate loss limits. Effective January 1, 2016, the losses on commercial related loans from The Bank of Miami transaction ceased to be covered under the loss-share agreement. Any recoveries, net of expenses, of losses incurred prior to January 1, 2016 on such loans will continue to be covered through December 31, 2018. The losses on consumer related loans continue to be covered under the loss-share agreement through December 31, 2020. Under the terms of this loss-sharing agreement with the FDIC, losses are shared on the acquired loan and other real estate owned portfolio up to 80 percent of the covered assets acquired. The losses on commercial related loans from the Old Harbor Bank transaction will cease to be covered under the loss-share agreement effective October 31, 2016 and any recoveries, net of expenses, on losses incurred prior to that date must be shared with the FDIC in accordance with the loss-share agreement through October 31, 2019. The losses on consumer related loans will continue to be covered under the loss-share agreement through October 31, 2021. Under the terms of this loss-sharing agreement with the FDIC, losses are shared on the acquired loans and other real estate owned portfolio up to 70 percent of those covered assets within certain aggregate loss limits.
Goodwill	Goodwill Intangible assets resulting from acquisitions under the purchase method of accounting consist of goodwill and other intangible assets (see “Other Intangible Assets” below). Goodwill is not amortized and is subject to an annual assessment for impairment. The goodwill impairment analysis is generally a two-step test. During 2015 and 2014 , Valley elected to perform step one of the two-step goodwill impairment test for all of its reporting units. However, Valley may choose to perform an optional qualitative assessment allowable under Accounting Standards Update (ASU) No. 2011-8, “Testing Goodwill for Impairment” to determine whether it is necessary to perform the two-step quantitative goodwill impairment test for one or more units in future periods. Goodwill is allocated to Valley’s reporting unit, which is a business segment or one level below, at the date goodwill is actually recorded. If the carrying value of a reporting unit exceeds its estimated fair value, a second step in the analysis is performed to determine the amount of impairment, if any. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying value of a reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded equal to the excess amount in the current period earnings. Valley reviews goodwill annually or more frequently if a triggering event indicates impairment may have occurred, to determine potential impairment by determining if the fair value of the reporting unit has fallen below the carrying value.
Other Intangible Assets	Other Intangible Assets Other intangible assets primarily consist of loan servicing rights (largely generated from loan servicing retained by the Bank on residential mortgage loan originations sold in the secondary market to government sponsored enterprises), core deposits (the portion of an acquisition purchase price which represents value assigned to the existing deposit base), customer lists, and covenants not to compete obtained through acquisitions. Other intangible assets are amortized using various methods over their estimated lives and are periodically evaluated for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impairment is deemed to exist, an adjustment is recorded to earnings in the current period for the difference between the fair value of the asset and its carrying amount. See further details regarding loan servicing rights below.
Loan Servicing Rights	Loan Servicing Rights Loan servicing rights are recorded when originated mortgage loans are sold with servicing rights retained, or when servicing rights are purchased. Valley initially records the loan servicing rights at fair value. Subsequently, the loan servicing rights are carried at the lower of unamortized cost or market (i.e., fair value). The fair values of the loan servicing rights are determined using a method which utilizes servicing income, discount rates, prepayment speeds and default rates specifically relative to Valley’s portfolio for originated mortgage servicing rights. The unamortized costs associated with acquiring loan servicing rights, net of any valuation allowances, are included in other intangible assets in the consolidated statements of financial condition and are accounted for using the amortization method. Under this method, Valley amortizes the loan servicing assets in proportion to and over the period of estimated net servicing revenues. On a quarterly basis, Valley stratifies its loan servicing assets into groupings based on risk characteristics and assesses each group for impairment based on fair value. A valuation allowance is established through an impairment charge to earnings to the extent the unamortized cost of a stratified group of loan servicing rights exceeds its estimated fair value. Increases in the fair value of impaired loan servicing rights are recognized as a reduction of the valuation allowance, but not in excess of such allowance.
Stock-Based Compensation	Stock-Based Compensation Compensation expense for stock options and restricted stock awards (i.e., non-vested stock awards) is based on the fair value of the award on the date of the grant and is recognized ratably over the service period of the award. Under Valley’s long-term incentive compensation plans, award grantees that are eligible for retirement do not have a service period requirement. Compensation expense for these awards is recognized immediately in earnings. The service period for non-retirement eligible employees is the shorter of the stated vesting period of the award or the period until the employee’s retirement eligibility date. The fair value of each option granted is estimated using a binomial option pricing model. The fair value of restricted stock awards is based upon the last sale price reported for Valley’s common stock on the date of grant or the last sale price reported preceding such date, except for performance-based restricted stock and restricted stock unit awards with a market condition. The grant date fair value of a performance-based restricted stock or restrict stock unit award that vests based on a market condition is determined by a third party specialist using a Monte Carlo valuation model.
Fair Value Measurements	Fair Value Measurements In general, fair values of financial instruments are based upon quoted market prices, where available. When observable market prices and parameters are not fully available, management uses valuation techniques based upon internal and third party models requiring more management judgment to estimate the appropriate fair value measurements. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value, including adjustments based on internal cash flow model projections that utilize assumptions similar to those incorporated by market participants. Other adjustments may include amounts to reflect counterparty credit quality and Valley’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time.
Income Taxes	Income Taxes Valley uses the asset and liability method to provide income taxes on all transactions recorded in the consolidated financial statements. This method requires that income taxes reflect the expected future tax consequences of temporary differences between the carrying amounts of assets or liabilities for book and tax purposes. Accordingly, a deferred tax asset or liability for each temporary difference is determined based on the enacted tax rates that will be in effect when the underlying items of income and expense are expected to be realized. Valley’s expense for income taxes includes the current and deferred portions of that expense. A valuation allowance is established to reduce deferred tax assets to the amount we expect to realize. Deferred income tax expense or benefit results from differences between assets and liabilities measured for financial reporting versus income-tax return purposes. The effect on deferred taxes of a change in tax rates is recognized in income tax expense in the period that includes the enactment date. Valley maintains a reserve related to certain tax positions that management believes contain an element of uncertainty. Periodically, Valley evaluates each of its tax positions and strategies to determine whether the reserve continues to be appropriate. See Note 13 for further analysis of Valley’s accounting for income taxes.
Comprehensive Income	Comprehensive Income Comprehensive income or loss is defined as the change in equity of a business entity during a period due to transactions and other events and circumstances, excluding those resulting from investments by and distributions to shareholders. Comprehensive income consists of net income and other comprehensive income or loss. Valley’s components of other comprehensive income or loss, net of deferred tax, include: (i) unrealized gains and losses on securities available for sale (including the non-credit portion of other-than-temporary impairment charges relating to these securities); (ii) unrealized gains and losses on derivatives used in cash flow hedging relationships; and (iii) the pension benefit adjustment for the unfunded portion of its various employee, officer, and director pension plans. Valley presents comprehensive income and its components in the consolidated statements of comprehensive income for all periods presented.
Earnings Per Common Share	Earnings Per Common Share For Valley, the numerator of both the basic and diluted earnings per common share is net income available to common shareholders (which is equal to net income less dividends on preferred stock). The weighted average number of common shares outstanding used in the denominator for basic earnings per common share is increased to determine the denominator used for diluted earnings per common share by the effect of potentially dilutive common stock equivalents utilizing the treasury stock method.
Preferred and Common Stock Dividends	Preferred and Common Stock Dividends In June 2015, Valley issued 4.6 million shares of non-cumulative perpetual preferred stock which were initially recorded at fair value (see Note 18 for additional details on the preferred stock issuance). The preferred shares are senior to Valley common stock, whereas the current year dividends must be paid before Valley can pay dividends to its common stockholders. Preferred dividends declared are deducted from net income for computing income available to common stockholders and earnings per common share computations. Cash dividends to both preferred and common stockholders are payable and accrued when declared by Valley's Board of Directors.
Treasury Stock	Treasury Stock Treasury stock is recorded using the cost method and accordingly is presented as a reduction of shareholders’ equity.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities As part of its asset/liability management strategies and to accommodate commercial borrowers, Valley has used interest rate swaps and caps to hedge variability in future fair values or cash flows caused by changes in interest rates. Valley also uses derivatives not designated as hedges for non-speculative purposes to manage its exposure to interest rate movements related to a service for certain customers, certain mortgage banking activities consisting of customer interest rate lock commitments and forward contracts to sell residential mortgage loans, and certain hybrid instruments, consisting of market linked certificates of deposit with an embedded swap contract. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Valley records all derivatives as assets or liabilities at fair value on the consolidated statements of financial condition. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income or loss and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. On a quarterly basis, Valley assesses the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. If a hedging relationship is terminated due to ineffectiveness, and the derivative instrument is not re-designated to a new hedging relationship, the subsequent change in fair value of such instrument is charged directly to earnings. Derivatives not designated as hedges do not meet the hedge accounting requirements under U.S. GAAP. Changes in fair value of derivatives not designated in hedging relationships are recorded directly in earnings. In 2012, Valley made an accounting policy election to use the exception under the ASU No. 2011-04 and calculate the credit valuation adjustments to the fair value of derivatives on a net basis by counterparty portfolio.
New Authoritative Accounting Guidance	New Authoritative Accounting Guidance ASU No. 2016-02, “Leases (Topic 842)” requires the recognition of a right of use asset and related lease liability by lessees for leases classified as operating leases under current GAAP. Topic 842, which replaces the current guidance under Topic 840, retains a distinction between finance leases and operating leases. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee also will not significantly change from current GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize right of use assets and lease liabilities. Topic 842 will be effective for Valley for reporting periods beginning January 1, 2019, with an early adoption permitted. Valley must apply a modified retrospective transition approach for the applicable leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Management is currently evaluating the impact of Topic 842 on Valley’s consolidated financial statements. ASU No. 2015-12, "Plan Accounting: Defined Benefit Pension Plans (Topic 960): Defined Contribution Pension Plans, (Topic 962): Health and Welfare Benefit Plans, (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient." ASU No. 2015-12 simplifies accounting for employee benefit plans as follows: (i) fully benefit-responsive investment contracts are now to be measured, presented and disclosed at contract value, (ii) the requirement to disclose investments that represent 5 percent or more of net assets available for benefits has been eliminated, (iii) the net appreciation or depreciation in investments for the period should be presented in the aggregate, but is no longer required to be disaggregated and disclosed by general type, (iv) if an investment is measured using the net asset value per share (or its equivalent) practical expedient in Topic 820, and that investment is in a fund that files a U.S. Department of Labor Form 5500, Annual Return/Report of Employee Benefit Plan, as a direct filing entity, disclosure of that investment’s strategy is no longer required, and (v) allows employers to measure (as a practical expedient) benefit plan assets on a month-end date nearest to the employer’s fiscal year end when the fiscal period does not coincide with a month end. ASU No. 2015-12 is effective for Valley for reporting periods beginning January 1, 2016 and is not expected to have a significant impact on Valley's consolidated financial statements. ASU No. 2015-07, "Fair Value Measurement (Topic 820): Disclosure for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)", removes the requirement to categorize within the fair value hierarchy all investments for which the fair value is measured using the net asset value per share practical expedient. ASU No. 2015-07 also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. ASU No. 2015-07 is effective for Valley for reporting periods beginning January 1, 2016 and is not expected to have a significant impact on Valley's consolidated financial statements. ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in the ASU No. 2015-03. ASU No. 2015-03 is effective for reporting periods beginning January 1, 2016 (with early adoption permitted), and is to be applied retrospectively. At December 31, 2015, Valley early adopted ASU No. 2015-03 to reflect the reclassification of the debt issuance costs from other assets to long-term borrowings for all periods presented in our consolidated statements of financial condition. See Note 10 to the consolidated financial statements for more details. ASU No. 2014-14, “Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure" requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. ASU No. 2014-14 became effective for Valley for reporting periods after January 1, 2015 and did not have a significant impact on Valley's consolidated financial statements. ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period" requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU No. 2014-12 became effective for Valley for reporting periods after January 1, 2015 and did not have a significant impact on Valley's consolidated financial statements. ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures" requires entities to account for repurchase-to-maturity transactions as secured borrowings rather than as sales with forward repurchase agreements and expands disclosure requirements related to certain transfers of financial assets that are accounted for as sales and certain transfers (specifically, repos, securities lending transactions, and repurchase-to-maturity transactions) accounted for as secured borrowings. The accounting-related changes became effective for Valley for the first interim or annual period beginning January 1, 2015. The disclosures for certain transactions accounted for as sales were required for interim and annual periods beginning beginning on January 1, 2015. The disclosures for repos, securities lending transactions, and repos-to-maturity accounted for as secured borrowings were required for annual periods beginning on January 1, 2015, and interim periods beginning after March 15, 2015. As of December 31, 2015, all of Valley's repurchase agreements were typical in nature (i.e., not repurchase-to-maturity transactions or repurchase agreements executed as a repurchase financing) and are accounted for as secured borrowings. As such, Valley's adoption of ASU No. 2014-11 did not have a significant impact on its consolidated financial statements. ASU No. 2014-04, “Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure,” clarifies that an in-substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, this ASU requires interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 became effective for Valley for reporting periods beginning on January 1, 2015 and did not have a significant impact on its consolidated financial statements. See Note 5 for the related disclosures. ASU No. 2014-01, “Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects,” amends existing guidance to permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense or benefit. For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the investment should be accounted for as an equity method investment or a cost method investment in accordance with Subtopic 970-323. ASU No. 2014-01 became effective for Valley for reporting periods beginning on January 1, 2015 and did not have a significant impact on its consolidated financial statements.
